i'm not too good at giving critism but ive been looking at this thread since it was made because i'm intrested in fakemon and i must say you are improving bit by bit and soon i hope to see some fakes of yours in hacks/games sometime soon ;).
your OW's are good not that i have any expirience in that but o well there good.
your reposes are good i like them nothing wrong with them i can see except the fist one the New Elemental Curse Hero is a tad too dark
Fakes: your shading is great but maybe make some of your fakes could have some unique things on them they look a little plain for example :
there could be a skull as a head or something to make it a bit more unique :?
sadly your trainer sprites need a lot of improvement no offense they look a little like a blobs ;) maybe look around for some Tut and maybe take faetures of other sprites then you can see where the features go on the body and stuff :)
i hope my critism helped :P
good luck with the rest of your sprites
