The Bellsprout is out of proportion, and it looks like it only has one leg. The Torchic is okay, but the head feathers need to look more feathery and the toes had to look a little sharper, it dose have claws on it's feet. I don't know what the third one is, but the face looks a little fat, you might want to trim it down a little. The Azurill looks allot out or proportion, try making it rounder. Again, same with the Luvdisc but a little better then the last one. The Gulpin is the most decent out of those sprites IMO. A little rounder and it would look good. You also need to work on shading; most of them look 2-Dish. Overall they need improvement but you definitely get an A in effort.
