When I made this postage stamp style logo years ago, I really thought my branding would lean more into the Stamps name and less into "every social media has that one cover art of the Mothman", but here we are. 😂 #indieauthor #artist #erotica #stamps
Digital art of a postage stamp-style sticker for an indie author. White text on a black background reads "SIBLEY STAMPS". Around the left and top sides of the ruffled postage-stamp frame, smaller black text on a white background reads: "Monster erotica est. 2020. Author and Artist."

I'm getting started on illustrating replacements for the two book covers I have that use stock photos. Here's a little sketchy Halloween Encounter cover mockup. Pascal manages to spend most of this book in that hoodie! #coverart #indieauthor #art #alienromance #tentacles
Sketchy cover art work in progress for Halloween Encounter by Sibley Stamps. A man drawn in purple lines and a woman drawn in gold lines are on a black background. The man is wearing a hoodie sweatshirt and hugging the woman from behind, smiling down at her. He had eight tentacles coming from his back like angel wings. The woman is leaning back against him and smiling. She's wearing a tiny French maid Halloween costume dress and ruffly hat. Several of his tentacles are reaching around in front of them, and she's holding a tentacle in each of her hands. At the bottom, large orange and yellow text reads: Halloween Encounter. Above, white text reads: Sibley Stamps.

We're starting the second half of the year, and I decided to shiny up the banner for my author newsletter! ♥If you're interested in things like monster erotica, alien romance, cryptid kinkiness, the Hat Man as a sexy sleep paralysis demon, alien abduction probing as a BDSM fantasy, the Mothman...
A banner image of several text-free book cover paintings of (from left to right) the Mothman, an Abominable Snowman, red tentacles, a UFO abducting a woman in a glowing blue beam, and a ack of three Dogmen. Bold bubble-like yellow text sits over the images, transparent and tinted by the blue UFO beam. The text reads: Sibley's Spicy Monsters Mailing List.

Sketchy cover art work in progress shot for the novella A Sparkler For Her Princes by Sibley Stamps. Two men and one woman stand on a black background. The tall man in red lines is hugging the other two around their waists. The man in blue lines is resting a hand on the woman's cheek and smiling at her. The woman in white lines is smiling up at the blue man with her hand resting over his on her cheek. The title text reads: A Sparkler For Her Princes. Sibley Stamps.

A snippet from my novella, A Sparkler For Her Princes. One of the two MMCs has blue skin, which is a genetic condition that sets him apart from their race of crimson red people. (Also, unrelated to the color thing, they've got horns and tails and fangs. ♥) #books #alienromance #bookquotes
A three paragraph quote from the SIbley Stamps books A Sparkler For Her Princes. It reads: They were nearly the same age, and yet their lives had been profoundly different so far. Wegg, crown prince of Jyrra and bearer of a royally vibrant crimson complexion, had been afforded every possible privilege. He had been taught about other worlds, piloting spaceships, intricate politics, and the rules of law. He knew everything he could ever need to become the next king of his planet, and then plenty of things that he didn’t need at all. 
By contrast, Tennoray had been allowed only basic schooling and whatever he might learn from extensive reading. No-one wanted their name tied to a Cold, not even tutors providing him an education. If not for inheriting his late mother’s considerable wealth and bearing the title of prince, Tennoray would not have ever even met Wegg, probably. 
He had, though. They had been dear friends since their teens. Wegg had become aware of how unfair and unequal their treatment was through years of observation, and he’d sworn to himself that someday he would change it. He’d thought that would be when he ascended the throne, but if he wasn’t allowed to marry with Tennoray, he wasn’t going to do that at all.

I kind of expected something like this. Luckily for me, most of my print books are already over $9.99, but I had to increase the paperback prices of my two novellas from $8.99 to $9.99 because I already make under $3 in royalties if someone buys them. #indieauthor #amazon #kdp #printbooks
A screencap of an Amazon Kindle Direct Publishing banner from the author dashboard. It reads: Changes to royalty rates for print books and color printing costs starting June 10, 2025. 

Starting June 10, 2025, we are changing the royalty rate for books priced below certain list prices (for example, less than 9.99 USD) from 60% to 50%. As a result, you’ll have books earning zero royalties after this change. To avoid this, you can update the list price for your affected print books. Separately, we are reducing color printing costs for paperbacks in some marketplaces. Learn more about royalty rate and printing cost changes.

I really appreciate the transparency about AI in this project. It sounds like the creators are being ethical about it, and only using their own training data or public domain data, and that's fantastic to see. This project looks very cool. I'm happy to see that it's getting funded! ♥
A screenshot of the Use Of AI portion of the Free5e Kickstarter page. The text reads: Use of AI
I plan to use AI-generated content in my project.
What parts of your project will use AI generated content? Please be as specific as possible.

Some of the audio used in the audiobook version is generated using AI that is trained on my own (Dale Critchley's) voice and then edited for quality.
Do you have the consent of owners of the works that were (or will be) used to produce the AI generated portion of your projects? Please explain.

Yes. We use elevenlabs.io for voice generation based on my (Dale Critchley's) voice. Evevenlabs has a FAQ for more information here: https://bit.ly/3PceLyr The model was trained on public domain voice recordings. I looked into this and have double-checked with ElevenLabs to verify the ethical training model.A screenshot from the Free5e FAQ. The text reads: Why does Free5e need a Kickstarter if it's free? The Kickstarter funds editing, layout, and professional human-made artwork, ensuring Free5e is high-quality and fully illustrated while remaining free. Supporting independent creators is important to us. It also covers print-on-demand setup, so physical books can be sold at-cost. Backers also get access to exclusive rewards like printable game tools, GM screens, and collectibles.

Thinking fondly of the time I sent this newsletter out on April 1st. (The story is real, by the way. I wouldn't get anybody excited for ovipositor space dinosaurs and then not deliver!) #AprilFoolsDay #April1st #smuttyreads
Newsletter text. 

We Created Them. We Couldn't Contain Them. Now We Have A Choice... Flee in terror, or stay and see just how compatible human and dinosaur anatomy can be?

Presenting... Impregnated By The Ovipositor Space Dinosaurs. When space station security officer Naya finds herself locked in with escaped lab monsters, she thinks it’s all over. The creatures turn out to be psychic space dinosaurs, though, and Naya feels an instant connection with them that is impossible to ignore… A giant red button reads: Get It Here! (This Is Not A Prank, I Swear. I Know It Looks Fake, But It's Not. Totally Real. Click And See. ♥) 

More newsletter text: Happy April, By The Way! We'll go back to our regularly scheduled newsletters after today. I just couldn't resist welcoming springtime with something egg-themed, even if that thing happens to be psychic ovipositor space dinosaurs (or, as my cover art seems to be screaming, "purple space Godzilla dragons." I'm not even mad about it...)

On the right is a metal sign that says "Caution: Dogman breeding area. Avoid eye contact." And in the middle are two neon signs, one showing Bigfoot in a yellow diamond "animal crossing sign" style, and the other that reads "spooky" with a ghost in the middle using the two Os for eyes.

I already had no interest in it, but after learning how it scrapes copyrighted real art (and pretty much all other pictures on the internet) without a right to use them, I have an ethical problem with it. Then I learned it overheats data centers so much they're using tons of water to cool them.

FontBase seems pretty nice, especially since it's free. It lagged out while copying my nearly 4500 fonts into the database, but now I can sort them into folders like Title Fonts and maybe have an easier time locating what I need quicker.
