War, Famine, Pestilence and Death. Quite minimalistic but pleasent. You captured the feel of them pretty well. I like Pestilence and Famine the best of the ones you drew.

I obscured War and Death so I didn't really have much chance to put detail on them. I think i'll widen the picture to bring them out. I was trying to go a bit Keith Haring but some of the figures are a bit weird.
