Man, sorry to say this, but they are very bad. But not as bad as some other.
And, the thread title says "Fusions" but examples 1, 3 & 5 are pokemorphs. Plus, example 2 is a recolor. I give you a 4/10. Oh, I almost forgot: save in BMPs or PNGs. Never, ever save in JPGs - they're for photos and such. And they ruin quality.
P.S - your sig is a li'l too big on the sides... do not delete your requested sprites, but... look at my sig, and you'll know what to do. I guess xD
