Carissa and her Mudcrab

My original characters, need to draw more of those two next time.

the story was:

Carissa Crabheart is a lady who fell in love with a talking mudcrab (what?) well yes a talking mudcrab, it's not just a usual mudcrab, it was a man that been cursed into a genderless mudcrab (of course it's genderless, it's a mudcrab after all, however we know for sure that crab's sex is male)

and the only way he's able to turn into a man again is to be pissed (literally) by a woman and will turn into crab again once the urine is dried up.
