NO THSE R NUT RLY GOOD LOL!!111
First off, you saved as a .jpeg. That is a mistake. I'm sure I would find these less annoying if they weren't in .jpeg format.
Because it is obvious you're a beginning spriter, I'll let your collection of pure recolors and Copy+Pastes go. But I suggest you stop doing them, because they require no effort at all. Work on something that requires more effort, even some fusions require more effort than that.
Frankly, your recolors require no effort, we'll ignore them. Your fusions are copy+paste. That can be a semi-good thing, if you can Copy+Paste well and make it fit in to the sprite. You also seem to like doing as simple fusions as possible. You want to make your fusions complex, but not overcrowded.
Instead of fusing Pokemon to make a Pikablu, try more to create new Pokemon using existing Pokemon pieces. Now I don't mean sticking a Pidgeot wing on Ledyba and calling it a new Pokemon. What you should try to do is use multiple different Pokemon 'pieces' and blend them together in such a way that it is hard to tell what parts it is made of. Recoloring, of course, does help.
