had an epiphany and threw together a quick meme edit
the old "Hello, Human resources?!" meme but instead the first section there's a guy saying "wanna see my dick", to which she calls human resources. The second panel is another woman saying "wanna see my dick" to which she says "Awww, you're so sweet."

Guess the cute octopus patterning on that cute swimsuit was more than superficial. ================== Gosh, I can't even remember when I requested this in a stream (8+years?) but I remember it was the first time that the wonderful @bozcat.bsky.social ever drew tentacles/octopi.

Putting on my little sex ed teacher outfit to remind people that a fairly large amount of trans women develop a broad, darkly pigmented line down their urethra and the center of their balls. It looks like this! I've still NEVER seen any artist add this to any picture of girl cock

A few weeks ago, I grabbed a freakier YCH slot than what I'd normally go for, and y'know I'm loving this. cw: transformation, hypnosis, mutagenic symbiotes in places they shouldn't be Art by DanDude from FurAffinity
A transformation scene, a trans woman with shoulder-length brown hair (my self-insert character, as always), leaning back in a dark cavernous scene surrounded by tendrils. In front of her face, there is a black tentacle with an eye on it staring into her face. Her eyes have hypnotized spiral patterns in them. Her nose is broad, bovine-like, and there are horns beginning to protrude from her head. Her upper body is being covered by a black, gooey substance, dripping from the tendrils. One of the black gooey tendrils, bulging in several places and carrying something inside, is reaching down into her girldick. Her balls have expanded out quite large into udderballs, covered in the gooey black substance, with four teats protruding out from them. One of the teats, her top right (or top left to the viewer) her hand wrapped around it and has a little tentacle coming out of it. Barely visible, since it's behind her, her arm has a tattoo of circuit-like patterns. Her feet have turned into hooves, and she has a tail laying across the floor coming around the left side of her. The eyeball has ominous text eminating from it, assumed to be some kind of psychic communication, saying "That's it, thrall. Let my seed flow into yours. You will make a fine breeder.".

I've been thinking I feel a lot more proud of my "messier" linework Pieces like this one, where I allow myself to be more carefree with my lines. I don't even know if it's something most people even think about or if it's just my own perception over my work.

Clicker Training Dog TF Commission from 2025 by AmbraNells #transformation
TRAINING DAY 1

illustration of a trans woman with light skin and brown hair on a couch
she has tattoos of circuits on her right arm

"Sorry Jean, looks like your little remote control isn't working on me. I'm not getting off this couch."

"It's not a remote, it's a training clicker for disobedient dogs like you."

"Yeah, even if I was your dog, I wouldn't be sitting and heeling for you. You're lucky I'm not, your couch would be torn to shreds."TRAINING DAY 5 

Trans woman with brown hair now sitting in the bathroom, with extra nipples growing below her breasts. She has some fur coming in on her arms, legs, and body. Her ears are starting to look more pointed, her teeth are are starting to get more pointed, and a tail is peeking out from behind. Her girldick is beginning to redden, and is leaking precum. There's a clicker in a hand sticking out from the right side of frame.

"Hey now, what did I say about touching without permission? Good dogs ask their masters first."
"Wuh... I wasn't. I'm good. It... it's been hard all morning.... please..."
"I'm not letting you make a mess of the bathroom. If you're good all day I'll give the puppy what she wants."
"O-okay master. I will be good."TRAINING DAY 11

Looking more and more dog-like, she's sitting on the floor of the kitchen. She has a blue collar on, and her tail is softer and more filled out. Her hands have claws on them now. Her nose is turning more and more into a snout. Her girldick is leaking cum profusely. She's. sticking her tongue out. 
A hand holding a clicker is sticking in from out of the left side of the frame.

"Good! Sit! Now open up that maw, I want to see how your tongue is coming along."
"Okay! Will I get a treat? Will I get pets? Aaahh- hoah's esh?"
"Good girl! Of course, you've been so good lately. I can tell you need it, you're leaking all over the floor."

"Eeee! Thank you! Arf-Arf!"TRAINING DAY 20

In a much more complete anthro form, she's now laying on the bed on her side. Her face has a mostly completed snout, her ears are prominent, and her legs are covered in fur. Her girldick has a knot now, and continues to leak.

"Please master... I... pet me, touch me. So very horny.... I'll do anything"
"You know you're not allowed on the bed unless I say so?"
"Arf!"
"But you do look really worked up and I've been wanting to find out if I can wrap my lips around that knot of yours..."
"Ah! Please! Please! Arf!"
