LOL! I love Kingdom Hearts, especially dearest Sora, but man, this is too funny. Very funny in fact... Donald totally needs to get out his anger in gory ways or something right?
Anyway, great style though influenced by Disney of course, to fit with the game's art. I like the fact that even though it's gory it's not sickening. The crimson color for the blood helps that. Unless you wanted it sickening, in which case you could probably darken the blood color a bit.
Other than that I really have nothing more to add... except that I'll have to look at the rest of your work now. ^_^
