very tight composition. It has a nice poster feel about it. Trust me that is not an insult in my opinion as I shoot a lot of that kind of thing. The absolutely only thing that distracts me is the missing top of the flag. Otherwise it would make a great ww2 style poster air piece.
The biggest problem all photographers have (Me included) is focusing to much on the center of their attention ie the sculpture. We all tend to not see the whole frame of the camera. In my case it was a bridal portrait with the back of someone's head in a corner of it. A mic cord running behind a person in the church, or best of all the telephone pole growing out of someones head in a street portrait. (actually it was a stopsign) that was pre photoshop by the way.
