AlphaBeasts! is probably about as close as I've ever come to painting a pin-up. Not exactly my usual genre! :-O
Sazae-oni is a shape-shifting bakemono who lives inside a turban shell. Sometimes she disguises herself as a beautiful temptress in order to lure sailors to their... dismemberment, shall we say?
I decided to depict the moment afterwards, when she begins to reveal her true, rather crabby nature to her poor victims. After all, vamping it up can be fun, but sometimes a girl's just gotta relax & be herself.
