Nah, they're fine as-is. The characters were always going to be smaller anyway.

Also, there might need to be a little bit of manual

tweaking of the Lost Soul's DECORATE lump as the flames don't animate until it starts moving, which looks a bit awkward. Might need C and D frames (alternate flame/tyre anims) to look decent ingame. But, yeah, as a (I'm assuming) featherweight class a la Toad in SMK it could do with being scaled down a bit.
