Also, the way you keep shading Gors literally makes him look like gelatin (and he's not made of goo ). You should find a different way to shade him besides the "dark color in the middle" technique. You could look at some of his own sprites to see how he shades Gilbert, and maybe you can make him look better.
Just my two cents. Not to mention, try what Viper suggested and not use black outlines. Instead try to use a dark version of the main color (and make it even darker than the shade color, but don't go so dark it ends up pretty much black).
