/ic/ - Artwork/Critique

I got told to not post in /beg/ so I suppose this is the right thread?

Anyway, I need critique specifically on the values. I look at this piece and can't help but feel there is something very wrong about it - and I'm guessing it is the values, since the proportions seem in place and also the head structure. Also, how do you organize your values on a portrait painting? I feel like I've rendered details before getting a solid grasp for the whole thing and this is fucking me right now (like the eyes and lips).
And how do you finish a piece? And I mean the refining part - how do you know which edges are supposed to be blended and which to be kept?

If you've the eye for any other inconsistencies however, I'd appreciate you point them out.
