My Fakemon sprites.

[Garamonde]

from what I can see right away, all the sprites have way too little contrast, and it looks like you tried to "blur" the edges of the shading, this isn't a good idea as it looks like you used a paintbrush. spriting is about making graphics crisp and sharp, and not looking Photoshopped. could also use more hue shifting. more info on these terms can be found here.
