For a first, they aren't too bad.
You're biggest problem is your leaving your outline all black. It's okay to have a little black in the sprite, but not the entire thing. You need to have some colored outlines. To see what I mean, look at the R/S sprite for Eevee and you'll notice it's outline isn't all black compared to your revamp. Try to work on that. :3
I see you changed the original shading on the Eevee. That's good, but the way you did it, it's a little flat. Or atleast to me. Like blazemxx said, try to identify the lightsource.
Otherwise, the Hitmonlee is a little better shading-wise. Except you yet again have the outline all black.
