I've decided that I'm redrawing those two Mamba backstory things I drew like, two years ago. They're at the very very beginning of this art book, at I think parts 3 and 4, so they're really old. Mamba's scar is bright red because he would've just gotten it-- it would be healed enough to not be bleeding, but fresh enough to not have scarred over just yet.
This is the old one. I've gotten much better at anatomy and just drawing in general. I'm honestly surprised at how little his design has changed over the ~3 years I've had him for
