I like this. The reflection in her eyes at first seems strange until it registers mentally what it actually is. :D Great clarity and detail. Good luck in the challenge.
She seems to look towards her left and not in her mirror at herself to apply the final touches. Somehow that detracts from the impact this photo has. Maybe because i don't get why she looks that way. (vote = 6)
The light is reflecting in the eyes which gives this a weird effect...like "red-eye" which has been converted to b+w...otherwise a creative composition.
