Yeah, this is one of the few shots of yours where a touch of Photoshop would be nice. Great relaxed pose where everything about the way you shot the model is perfect, it's just the color of the graffitti which brings the image down. I would have liked a shift to stage left as well, except then the large round brown mass would become too prominent.
Still a great example of how to work with a model. You seem to have a knack for that
