Not a bad idea but in my opinion I would have preferred this if it were not so tightly framed, it´s hard to get a context of where she and the dog are standing as it is now. What I am trying to say is that IMHO you need to show if she 100 stories up or is this just a threshold, do you know what I mean? Also the lighting is good but the flash shadow is never good to have so I deducted 1 point for that.
All in all a very good idea but not executed as I would have preferred it. Keep up the good work!
