It's fairly under-exposed for my liking, for that you get a 6.5/10
The shot itself though; composition, the feel and the quality, if the exposure was higher I wouldn't hesitate giving a 10/10. But saying that, I feel it's the style you're going for with the previous shots also, so I can't really influence anything with that.
Another from my selfie session...
*Not high ISO, I just love the grain effect on B/W*
