Very nice piece, and looks like it would make a very nice 3D print, too.
My only gripe with this work is the trunks: they look too vague, a simple wrinkly mass. I understand that they’re mostly hidden in the final sculpt, but I still find them the weakest part about this piece.
You can still leave them a wrinkly mass, just make the wrinkles form a pattern that looks like clothing.
Here’s an example of what I mean (it’s a picture of Sabu from “Thief of Bagdad”, I don’t know the proper name of that diaper-thing he’s wearing). And another example.
Everything else you’ve done with this sculpt is stellar, I think it’s a shame you let the trunks remain so crudely rendered.
