That's pretty good! I love the attention to detail in the two death poses. Though if you wouldn't mind a suggestion, I think skins tend to look better in-game if they've got an outline. Unless there's some particular artistic reason to forego an outline, like there is for your Bugdroid skin, to match the source better.
The Quote skin also looks excellent. Even if it's just an edit, it's a well-chosen one, because Quote seems to fit right in to the SMW world. (For some reason, the lack of an outline doesn't bother me so much with him, probably because of the really stark contrast of colors.)
