Your sprites aren't really that good... The first trainer sprite looks okay, I guess, but it isn't really a masterpiece either. The colors don't match at all and it somewhat lacks shading. The second one has pretty good shading, but there's something that looks a little weird
what's the spot, I just circled doing there? It looks like shading, but if it is, it certainly shouldn't be there... And there are some colors in the hair that looks pretty messed up...
Your fusion is great though, but the shading is a little off there too. The spot in trapinch's head that you have colored with a dark shade should be light, and the head should cast a small shadow over the hand.
The recolors are really great (and I mean it) but the format you saved them in makes them look fuzzy, use png or bmp and you'll have some great recolors ^_^
The shadow pokemon aren't good at all, I think. The colors on Blaziken are just horrible and the shading... needs some work too. I hardly need to tell what's wrong with an inverted Scizor, but it would look much better if it had more shades and if you'd switch the shades so that they look proper (by that I mean, you switch the lightest and darkest shade and the second darkest and second lightest and so on...)
I give your sprites 2/10 you are a great spriter, you just need to put more effort in to them. If you just don't get the hang of shading, I suggest you look at official sprites and try to figure out how the shading works. Well, I wish you the best of luck ^_^
