I like #3 and #4 most.
Number 3 took me a while to figure out >.< aha, but that's why I like it; it's a bit different. I think my vote goes to number 4 though, a bit easier on the eyes and it looks nice
I liked number 1 the best x) Even though the brushing kinda takes away from the focal of the eyes :S
