Nobody likes an enemy. 8 colors, 9 including transparency. The "face" was rushed, and I couldn't settle on a singular light source. I regret both decisions, but overall am happy with the way it turned out. CC is always welcome!

EDIT: I don't think I should have added this to this week's challenge. The idea was vague to me (damn you, subjectivity!), so please skip this submission and vote for those who put 1 and 2 together, haha. But please, comments and ratings always welcomed!
