Sara Mapes, a fellow livestreamer on Behance, created a draw this in your style challenge that I decided to take part in. You can see her original illustration below of her moon puff. If you'd like to participate in the challenge, be sure to tag your work with #maperrsDTIYS.
We worked on this during my livestreams. I started the sketch and blocking in the color in Adobe Illustrator on the iPad, and then used Retro Supply Co Gouache Brushes in Adobe Illustrator on the desktop to add some texture and shading. You can find the links to the replays here: Part 1, Part 2.
