This is quite nice. But I'd like to see some stronger highlights on the hair and some deeper contrast on the face and neck area. If you have the beginnings of a tattoo on the shoulder then I'd like to see where you take that too. Nice!

Looking at the tiny thumbnail on the main forum of this image, the most noticeable problem is how much his right sterno-mastoid stands out. Particularly compared to the soft & rendered face, the neck seems flat, so you may want to look at some neck anatomies.
The face is nice and elegant, but it's getting a little long in the nose. This is really easy to do, unfortunately, but a good way to avoid it is by looking at the distance between the tip of the nose & the corner of the eye.
Another thing you may want to watch out for is using too much white in the highlights. Right now, the light on his cheek makes it look as if there's a strong white light right next to his face, but the light on his hair indicates that it's a softer light coming from above. Sometimes it's good to make only the area closest to the light really bright, and leaving the highlights in other areas less intense.
Hope that helps '_';
I like the softness of this piece.
His left (our right) eye looks a little long to me, like there's no perspective going on. It doesn't seem to me it'd stretch over to the other side of his face like that.
I would say make the stark white back ground slightly off white to make it less intense to look at.
