If you are going to take a picture of your self in the mirror as all of us photographers do at some point in time. make sure to mirror the image back or you will see that the words are backwards
Looks like you're a person with a mission looking at the facial expression! Nice shot but I would have moved over a bit to block the light on the right side it distracts.
Is that mirror dirty? seems to take away some sharpness, or maybe it's not entirely in focus. anyhow, nice use of contrast, composition is a little boring for me, can't give this more then a 5.
The background trim piece's intersection with the subject's head is distracting. I'm also not comfortable with the way the camera is cut off, and a partial finger is showing. I think a different perspective and some cropping would go a long way.
