Yup, so you came here for criticism for your sprite work correct?
I'll start with the starters. (Note that I'm telling ways to improve your work)
The grass starter is great. It's cool, nice and cute. But its size is to be shortened out, not the body, but the whole thing, because when I play your hack I wouldn't want to see starters with high resolutions. The fire starter is not only too big in size, but also in structure, because it looks like a second evolution.
As for the Fakemon... well... some of them don't look like first forms, and some of them are still oversized. The outlining is jagged, and also you could use a nice selection of colours and fix a little inconsistent shading.
Look to see more!
A bunch of these went through a few revisions from smaller versions, but if they are made any smaller, details on them disappear and they look rather horrendous. But that's just what I found.
