This is great

this here be some batman level antagonist going on. my only question is are you going full joker where even he doesn't fully remember his own back story and how he got his claws, or are you going with something fucked up but clearly defined. just don't make him in to some generic slasher banana and nut bar villain that just gave him self his claws so he could more efficiently un-alive random nameless background characters. and don't make him eat people its so been done, its not even scary or compelling since the twilight movies.

Is he a natural born predator or a machine built one?

Those are some snazz claws you got there

fantastic coloring!
