It's quite good, really. There isn't much critique to offer about it, from my point of view. It's pretty stylistic, and your technique is fairly strong. Only thing maybe, is that the right hand side of the image should be cropped a little bit. Otherwise, I dunno. Hair normally has a 'glossy' quality to it, but you probably omitted that intentionally, so...
