NEW SONA!

I still love bats with all my heart but I’ve been a bat for seven years now and I decided I wanted to change it up a little so uh here’s the new me! I am now a weird blue dog! You can still call me Kitty though!

(Thank you so much to @coyotemasquerade.bsky.social for the wonderful art!!)

Wooooo Wroaw?

#myart #ocart #animalart
A single page comic with four panels. Featuring my original characters, Stevie and Sammie. The top three panels feature Stevie, a borzoi like canine with golden brown and white fur. She at first pulls her ears back in concern, a thought bubble above her indicating she is wondering where Sammie went. She then calls out “Wooooo Wroaw?” and perks her ears straight up, looking alert and listening attentively. In the final largest panel, lush overgrown grassy area is shown, The grass is tall and green and mixed among it is flowers and twigs. The sky and some trees in the distance are visible as well. Peaking out from the glass on the left, Sammie’s ears and tail can be seen. She is a small feline like creature with dark brown and gray fur. To Stevie’s question she replies “Meow Meow!”

I hope they use AI in the next star wars movie. After Rise of Skywalker I’m morbidly curious to see how bad star wars can get.

exponentiation was invented to transform the easy problem of addition into the difficult problem of multiplication. before exponentiation, mathematicians had no idea how to make it hard to add numbers. #AmazingApplicationsOfMathematics

back view and swtor dootifur form!

#myart #ocart #flimflamstrawberryjam #swtor #swtoroc #knight #dateknight
Digital art featuring my ocs Dragon Knight and his small companion, Dragonito and some additional details. On this page there is both the front and back view of Dragon Knight, showcasing his armor from all sides. It is two layers, red underneath with black material on top. The black material nearly covers all of him and it has an iridescent shine to it. The red layer that is visible has a grid or web like pattern on it. He wears a helmet, it is all black other then a red plume and glowing red lines on the screen like window where his face would be. On the front facing view there is a back and red sword at his waist. Besides the back view of him, there is a full drawing of the sword. It is black and red with an iridescent shine to it and something looks like an eye near the handle. Dragonito is besides Dragon Knight on the right. There is two forms of them shown here, depending on the setting or universe they are in. One is the SWTOR (Star Wars The Old Republic) form, in which they are a mouse droid with black armor and a glowing red light. In the other form they are small, boxy, train like, and also vaguely guinea pig shaped. Around the same size as one as well. They have four wheels. Their armor is also also black and red, with a screen like window at the front that has glowing red eyes. They have a tail that stick up with its own small red plume as well.

kinda sucks that my human neural network has now ingested enough training data that I can instantly clock AI writing and that I end up making use of this ability fairly frequently

Dems should offer $6K. If Trump ups his own offer just keep raising until either it becomes very obvious all of this is fake or the bond market explodes

Digital art featuring an adopt design. There is a fully colored headshot and full body reference. This creature is a tiger with purple plasma ball and lightning inspired markings and pallet. Their pallet is made of very dark black blue, purples, blues, pinks, and white. They have a single horn on the center of their head. In the small full body reference, there is a white orb floating above their horn with what seems to be lightning or electricity emanating from it.

Finished ref sheet commission for @sagadoggie.bsky.social 💖🙌

Was sooo cool getting to work on this, thanks so much again for commissioning me!

#myart #ocart #artcommission
Digital art, a reference sheet commission of a bat character. This reference sheet has a blue background, with a decorated border. There is 5 drawings of this character on the reference sheet. A large full body drawing shows him standing, facing the viewer, one winged arm lowered and the other outstretched. He smiles and has a overall calm expression. His top fangs sticking out slightly from his mouth. Fur color is a variety of warm browns. Getting darker near the ends of his wings and feet. He has four eyes, two larger ones and two smaller above those. His eyes are turquoise in color. He wears two robes. A blue one with a hexagon pattern on top. It almost entirely covers the gray one underneath. Behind his full body drawing, there is four floating 3d rectangles. The are lined up behind him, each a very dark blue, with a glowing circle on the top half. Below there is a blue line indicating their number, from 1 to 4. There is also two busts of him as well, one with a calm smiling face, his head tilted to the left. And the other with a snarl, teeth bared, expression intense, and his head lowered. Finally there is a color pallet, which is several hexagons connected and filled with colors, along with a mini front and back view of him without his robes. Showing the markings on his entire body.

This hellspawn took 30 mins to even hit the 5% encounter chance, KOed half my team with crit quick attacks, ate five great balls, five poke balls, and four timer balls, and then finally let itself get caught on my literal last ball. Welcome to the team you little freak.
