Finn sprite is fairly decent, but not JUS style.
Crash is recolour. 'Nuff said.
Nice work on Spy vs. Spy. Use straighter lines next time.
I don't know Crazy Dave, so I can't comment on it.
Dr Wily is just all kinds of wrong. You used his head from the Mega Man arcade games which have the sprites all stretched, the pants are too straight and make his legs look fat, his shirt and pants are pillow shaded, his shoes are bleh, his coat makes him look like Quasimodo, and he looks hideously deformed as a whole.
