Random doodle.
This one looks like Princess Donut from Dungeon Crawler Carl. This book is the Venn diagram of the books that all of us loved. Super fun.
I'm surprised how when I use a sketchbook's back page basically to test media, I end up freed from the pressure to make anything "good" and as a result, the doodles that end up there sometimes tell their own story that I look back on much later and remember.
