I love everything about this shot! In general I tend to prefer to see the subject off center, but here her location really works for me. I also like the background. It's blurred enough that she stands out from it but you still have context - it's a great scene, not just a picture of a pretty girl. Maybe it's a tad overexposed, maybe it's a bit grainy, but not too badly in either case and I feel it adds to the feel of the shot. And honestly, if nobody had said anything about her hand position I wouldn't have thought twice about it (and I still don't find it that bad).
