oh man, you and Subomi~Chan are pressing my nostalgia button~
You're very good at outlining, though there are some flaws. Patamon and Gabumon's left arm (our right) is jaggy, Palmon's head is too blocky, Agumon's arm looks way too much straight, and Graymon is alright, I guess.

now for coloring, your contrast needs more work. Your shades are hard to notice (see Palmon), increase contrast by hue-shifting (push the darker color more to the blue, it should work). I suggest you shading the outline too. It'll make your sprite look better.
