Totodile looks great.

Cyndaquil looks a bit odd considering the unusual pose, but OK. Maybe define the thighs/hips a bit more - it looks like it has a shell.

Chikorita looks hideous. No disrespect, but I thought that its right forepaw was a saggy breast at first glance. Its forearms should be as big as its hind legs, if not bigger:





Also, the eyes make it look like Dr. Insano, and the leaf is bent. Chikorita's leaf has a slight curve. Bayleef is the one with the bent leaf.

Take it slow, Gabi. Pokemon proportions are damn-near impossible to get right, especially after only a day's work.
