Cat.1: Good all out, not very weird 5/5
Cat.2: It looks OK, but I don't see much change 3/5
Cat.3: It's weird that I think it looks cute, but it's head seems dis attached from the body 3/5
Cat.4: Eh, you really just made the hat bigger, added legs, and a little brand mark. 2/5
Cat.5: It looks like you didn't put any effort into it at all. 1/5
Cat.6: O_O That looks weird... 1/5

I think the first, second and last are the best.

@Dewott: Cat 2: I add that Gray thing from Entei and the thing on Suicunce's head. Cat 3: Well I didn't spend too long on it. Cat 4: I also did add new legs, and that little silver thing. Well the last one was the Cat for the 15 Pokemon so it hard to do so.

@Spirit: Thanks those are my favorite too.
