Delicious Rainbow Core
This is a resub. This was submitted so long ago that it was my old Threadless account. I decided to redraw the entire thing from scratch based on the great feedback I received (i.e. "the foot is posed weird, the shadow is wrong, etc.").
Here, I tried to capture that old-timey "etching" feeling, as if this image was found in some sort of insane encyclopedia about mythical creatures. Best on some sort of gray, heather gray, or slate blue shirt color. Enjoy!
