I don't want to repeat what other people have told you, but I do agree about the over-exaggerated body-parts, they don't make me uncomfortable as much as that it looks unnatural.
What I do like is the way you did May's hair, it's a nice twist. Cynthia's should be longer and have more volume though, and some of the strands simply seem to go nowhere, like the random straight strand that disappears. The pants have one hell of a wedgie going on, that ought to be painful, but okay. Gasterodon = win.
In the snow picture of Dawn it looks like she doesn't have any clothes underneath her jacket, which is really odd (Especially since it's snowing). Beside the Piplup, which is shaped a bit oddly, I really like the Pokemon in this picture, especially the Spheal that's just popping up there, it's adorable! And the background is pretty good too.
The Fantina picture is pretty good too, I love the faces of the Pokemon, they look awesome, and her pose is pretty good too, even though she looks a bit short. The boobs don't even look quite as apparent as in the other ones. They only thing is that the folds of the dress around the stomach are rather odd.
Overall I simply love the way you draw Pokemon, it takes a humorous turn. You do hands rather well too, which deserves a mention because, for me personally, they're the hardest thing. What you should work on is anatomy, and you might want to tone the amount of folds you put in, there's an excessive amount in some places.
Keep going and practicing, you can only get better.
