Haha, Walnut's right and now I can't look at it any other way D:
As far as everybody's edits of Zecco's slime, they're only "better" if more 3D dimensional is what Zecco is going for. If you're trying to emulate a really old-school, simple style, then you're doin' pretty well. If you're going for more modern graphics, then Skeme's edits are definitely helping you get there.
Also, skeme, I see where you're coming from with the super vivid green in the middle there, but it seems a little TOO much to me, too. I agree that it should be light and bright because it's reflective, but I think it should be just a tiny shade darker, or the surrounding area a shade lighter.
Maybe.
