Is it just me that notices things like what appear to be paw prints on the wall, what looks like a bruise on her shoulder, and the deep shadow of her arm on the wall? I think all these anomalies, plus all the grain /noise detract from what could be a great picture. I think the basic concept, framing, sepia color, low key treatment are all wonderful, but because of the problems, personally, I would regard this is as just a good first draft, and that if at all possible, the OP should get someone to re-shoot it who could implement the concept better and come up with a real winner.
This was actually taken during a concert and the original photo is low-quality, so there's not much I can do about it. The thing on the wall is a slide show (that also explains the weird shadows). However, it's all fine to me as the photo is just a nice memory for personal use.
