I like the first one, but you might want to crop it a little moe so there isn't so much negative space on the right side of the frame. You could also try a high contrast technique Kelby uses. Duplicates the layer 2 times, make the one in the middle B+W, make the top layer either soft light or overlay, then mask out the eyes in the two layers to get your natural eye color. It looks pretty cool when done.

Hope you didn't mind but I did a quit touch of what I was referring to...I'll take it down in a bit
