My first question? What do you want to show on this photo?
Secon: How much have you manipulated it by computer and how does the original look like?
Third: Who gave that bruise to the girl? It was given by photoshop, am I right?
Fourth: Lets assume that the bruise was caused by some wierd circumstances of light? Was you intention to show a girl beaten up? (that is why first question was asked for)
It looks like it's just a shadow and not a "bruise." The photo looks as though she is waiting for her ride to get there so she can go to the movies or something like that. Nice photo.
