Don't know if I like the hair colour, but I like the framing effect you've created. The slight covering of your left eye and part of your lips brings about a mysterious feel. Oh and by the way gorgeous eyes :)
Fun shot, the colors work well here. As everyone has already mentioned awesome eyes... I will go one further a say your thick dark eyebrows add a lot of impact to your shots. Great shot, keep em coming.
I think I figured out what I like about this. The electric blue hair meet a face with pretty standard makeup, just a bit of lipstick. The juxtaposition is nice, and not really noticeable at first because of the understated nature of the facial feature next to the insanely blue blue. I like it.
