NEVER use paint's default colors, only when your doing pixel overs, or in early drafting. uhh Do you know how too recolor properly? here, some good tuts to help you improve.dragonflycave tutsPMF.inc
Hmm..They aren't too bad for your first. But they looked very copy and pasted, and you need to recolor properly. Follow the one of the links ~*Lovély_Latias*~ provided.
All it looks like you did is copy and paste the body parts together instead of recoloring them to make them look like they go together. But, for your first ones, they aren't that bad.
You need to recolour the pasted body parts e.g the golbat wings on scizor. Also what the hell happened with tenta champ. apart from the hideously eye stinging colour and lack of shading, you could have at least got rid of the tentacles to make it look less copy+paste. I take it that was your first one. they look like you didnt put a shred of effort into them and i have seen better for first sprites. You could have done a lot better. 1/10
