I felt like doing a scene flip animatic of a segment out of @mikeysota.bsky.social’s demo reel. Starring Reggie and James!

Happy birthday dude! 🎂🎉

Seems like @cinna-cat-racc.bsky.social is witnessing a giant problem! I sure hope James is quickly working on a solution to this…

My half of his trade and a little contribution to #MacroMarch.

What’s this? Aisha got a redesign AND a turnaround ref? What a way to start off the Elephant’s March!

Reggie in Pokémon Trainer attire standing next to a Dragonite back to back, tossing and catching a Pokéball in the air simultaneously.

Happy Pokémon Day! (This took so long to make.)

Reggie meets his old self! **INSTANT REGRET**

It felt so weird drawing my first attempt at Reggie after almost a year and a half.

Reggie now in rendered form, hope you like it @apetersenyt.bsky.social

Reggie, my silly dragon. RULES - Absolutely no NSFW/Fetish. - Do not make gory content. - You can change the pose to whatever you like as long as it’s SFW (proper ref linked in reply).

I’m gonna do one of my own. Rules in ALT!

If you see this, post your painting/drawing of a dragon🐉

I mean, it’s quite obvious.

Welcome back artists! 🖌🎨✨️ Quote post with an old piece that you still like!

This was for 9/11 this year, and I’m still proud of how it turned out. It’s still my iPad Lock Screen after 4 months!

Reggie is standing in the middle with Christmas lights and decorations wrapped around him. Cooper and Lilly sit underneath him laughing with joy, with presents in the background. Merry Christmas! 🎄🎁

Merry Christmas (Eve) everyone!

I was originally gonna publish this tomorrow, but I heard it’s Christmas in Australia and parts East of the world. Hope you all have a good one!

Reggie doodles.

I’ve always wanted to draw Lilly hugging Reggie. This is especially appropriate for today because they are both thankful for each other.

Happy Thanksgiving to all who celebrate!

Various Cooper sketches.

#CooperLillyShow #cartoon #sketch #ArtistonBluesky #smallartist #cuteart #digitalart #cat

Concept art for Reggie’s nighttime fit. He wears a blue onesie with stripes along his belly and stars on the outside, a night cap, and bunny slippers.

Concept art for Reggie’s pajamas. Might do it for all the other characters as well.

Cooper, James, and Lilly are all dressed up for Halloween. Cooper is a vampire, James is a skeleton, and Lilly is an angel.

Don’t be alarmed when you see these fellas show up at your front doorstep.

Happy Halloween!

Cooper and Lilly in the style of @bakertoons.com!

Thank you Charles for coming up with this challenge. I had a lot of fun participating and thinking differently on how to draw my characters.

Cooper waves hello!

This is my very first decent attempt at hand-drawn animating a character in over 10 years. And I’m already hooked!

Aisha in her Halloween costume; a witch! She is posing menacingly whilst grabbing her cape with her trunk.

Aisha bewitched!

James is solemnly saluting Windows 10 and its impact, fighting back tears. Underneath the Windows 10 logo are the dates July 29, 2015 and October 14, 2025, the duration of Windows 10’s service life.

Today is the end of support deadline for #Windows10. I’ve had so many memories using the OS from Christmas 2015 all the way until Christmas 2022 when I upgraded to 11. It will be missed.
