Agli-Gor: imp jester, friend to all, had but one talent in life: to get away with jokes that would (or should) get any other comedian killed.

A reminder that you do not have to interact with every negative, idiotic take on the internet. In fact, you shouldn't. The less reactive you are, the better your life will be.

Willing Subject
A dark room, lit by a single shaft of light from above. A man laying flat on a stone floor, next to him is a sorceress on her knees, dagger up in the air, an instant before she plummets the blade into his chest. The man stares at the viewer with a content expression. Next to the man's hand is a tipped over goblet.

illustration of death carrying a soul away to the afterlife. black background, theatre light over a fallen soldier with an arrow on his groin and head; he lays limp on the floor, his eyes vacant of life. death appears softly from the black, hovering up as she carries the same soldier as if he was weightless. the soldier has an expression of shock as he notices the skeletal hand of death clutching his nude body.

gnomish settlements are reclusive; concealed by powerful illusory magics. there, the small denizens scheme and toil incessantly on ways to locate and return to their utopic homeland. any gnome may leave, but they must first undergo a ritual where all memories of home are erased from their minds.
digital painting of a gnome walking into a sunsetting grassy field with a dog companion twice his size. the gnome wears a starry hat, hands clutched behind his back. he looks behind his back with a slightly  melancholic stare, but his pose indicates sureness of his movement. the dog looks straight forwards.

Wake up babe, synopsis for OTTO NUMBER 9: a new adventure for OMIOS URES just dropped. As always, I'm having a lot of fun with the layout/illustration juxtapositions. Coming soon!
Page spread with a black and white illustration of a cablecart travelling up a wayline to an enormous tower with a bulbous rooftop in an enormous cavern. Text reads:

A NIGHT TO REMEMBER...

Welcome to Bugram Agar. The brightest star  in the underground sky. One night here costs about as much as the average worker earns in a year, and this will soon be a night to remember.

A microcosm within a microcosm, Bugram Agar is the Karamouski crown jewel for game and opulence. The Hotel hosts the Opal Casino, thermal pools heated by fiends in captivity, a grand auditorium entertaining exclusive concerts and plays, a pleasure dungeon and, perhaps most importantly,

Utmost privacy.

The building perches alone on a reserved cliffside, away from all the buzz, low-lives and unexpected smells of the big city. A gilded cablecart, privately operated, fetches the richest of the rich to and from the nearest district of Portnova, way above the underground clouds, up into luxury nirvana. Please take your sick philter, enjoy the complimentary aphrodisiac and avoid looking down at the 300 meter tall fall.

Tonight, a great tragedy is set to take place. For the first time in centuries, a mythical, near-indestructible defense automaton named Otto Number 9 will be seen by the public eye, and more: it will be the centerpiece of Bugram Agar’s bi-annual, highly-anticipated Grand Auction.  

But no one could predict the Machine would awaken from its thousand-year slumber.

It is now up to the Party to put a stop to Otto’s carnage, or simply make it out alive, all the while three tonnes of rogue metal rampage the carpeted halls of Bugram Agar.

Traditionally, Carverine engrave their tusks with biographical glyphs and runes, so that their bones may tell stories of who they were in life. In more cosmopolitan settings, however, tusk engraving often serves less ritualistic, more decorative purpose, akin to some human tattoos.

This is a multimedia piece I've been wanting to do for months, character is painted in acrylics on a digital photo manipulation printed background. Also, it's been a while since my monthly experiments had a more playful tone!
Multimedia painting on vertical canvas
Theme: Fantasy / Dark fantasy / Experimental
Character: My OC Lubi, he/him, transmasc
#Artsky #QueerArt #TransArt #DarkFantasy #SwordAndSorcery

This is a mixture of digital and traditional process. First I edited a photo background and added a digital line sketch, which I got printed on imitation canvas, and then finished by painting the character with acrylics. The piece is pretty big - 104 x 139 cm.

The background is a photo of an old wine basement, appearing like a cave with brick walls. I edited it to get a blue and green-yellow palette.

The character is sitting on the floor in the center of the cave, grinning. The nose, mouth and eyes are the only other part of this piece that was done digitally, as I was unsure if I could paint the sharp edges of the design.
He's wearing a hooded cape, which gives the impression of an invisible coat, as its colours reflect the colour of the background in a blurry way. He's wearing a black shirt which extends into a loin cloth with a green, zig-zag edge. The shape of the hood covering his face is a heart. His face is partially shadowed, while red fiery hair is sticking out on the leftside.

He's wearing gauntlets, which are shaded in much more delicate detail than the rest of the character. The metallic shading also extends to the wavy-bladed sword. His boots are red and black, with a somewhat checkered pattern.

Behind him is a wall which is transparent in the middle, having a dreamlike impression. On the wall of the cave which took on the greenish-yellow tint in the photomanipulation process, I painted a torch with a green flame. On the upper left part of the painting is a yellow moon crescent.

Lastly on the top right edge of the painting are a couple of crystals, catching the colours of their surroundings, which makes them almost invisible until you notice them. I really love how these turned out.

Never forget that they had to spend trillions of dollars, build massive data centers, consume millions of galloons of water and insane amounts of electricity, just to kind of do what you can do better with your imagination and a cup of coffee. That's how envious they are of what you can do.
