I rather like that Nohface sprite; it looks crazy cool. I don't quite mind the wisps in it, or that he has a body. I think having a body is kind of important for a Pokemon, and think that a disembodied set of masks would be very confusing for the Pokemon. It'd remind me a lot of like... Dugtrio. Except that, instead of evolving to gain more heads, it'd lose them? That seems weird to me. I say keep the body, or at least try versions of both.
Also, Wyv, the proportions of that Pyroak bother me a bit. The shading and shape of the head suggests that he has it cocked to one side, which looks weird. The arms are huge, too, and I think that the legs are having vanishing point problems. (too big in front and too small in back) All over I get that "looks funny" vibe, though, which I think definitely needs to be addressed. I think fixing up my previous points might be a good start. I like the work so far, though, but miss the cannon-aiming pose. ;_;
