Ooh, I like this hack! It looks promising, and although there's not much to see in terms of Fakemon, plot, or dialogues yet, I have high hopes for your success!
The real reason for my posting, though, is this:
I saw your trainer sprite and thought I'd edit it for practice. I'm not the best spriter, and my human anatomy isn't perfect, so my word is far from absolute but there you go.
To the left is your original, the middle is my edits with the original palette in case the sprite is indexed and you can't change it, and to the right is my edits with palette fixes, because saturation, contrast and hueshifting are your friends and you should never use full gray for anything. Also I wasn't really digging that green.
Hope this helps! Feel free to use it however you like! Oh, here's a tip: when you sprite, do it on a nonwhite background. Helps a ton with the outline!
I'd love to see sprites and stats for the fakemon! If you want any more crit, just ask!
