wow this is beautiful, good composition and lighting the only thing i can tell is that its a bit crooked or is that just the way the walkway is. Do you mind posting your setup?
The shadows don't follow the lighting. she is lit from the front and her shadow is on the front. She has a nice bright leg with a shadow coming from it, and then a shadow from her other leg casting on the one she is standing on........if any of that made sense
