This is a tough image to critique because I really like it and it works overall to such a degree that I am really working to find ways it could be better. I think the only thing about it that niggles at my training and eye is the hand. Having it cut off like it is... it's a bit distracting. I would rather seen the whole hand (or at least the whole finger) or just the side of it. The finger is wonky but easily fixed with a slightly different crop (which would likely happen when printed anyway).
I like her look and while I usually prefer my models to look at me for these kinds of shots, the looking away works here quite well. I love the texture of the hoodie too, sometimes these more washed out b&w images can lose that texture but you've retained just enough of it to move it to a higher level. Good job.
