Cool gallery you've got here, ZKE! I don't know much about spriting, but I think you've put quite a bit of thought into your designs (a conclusion I've reached just by looking at them, lol). They're pretty detailed, and I get the impression that each evolutionary line belongs to "a bigger set", like from the same region - which is good, since it shows that you have consistency and that every fakemon gives off a somewhat similar vibe.
Anyways, the Izaga Region's Pokemon differ from the regular/official Pokemon in terms of style, so it was interesting to see what you have already in your Fakedex. Kotsuba and Mewthree in particular look awesome.
As for your trainer sprites, they look good as well. There are a few flaws I've spotted here and there, such as awkward-looking hair and outlines, but the designs/concepts themselves seem pretty solid to me. Keep it up, dude!
