Hi Manuel,
I think this is very refreshing photograph, particularly as model photography goes.
So often we see pensive looking young women posed against plain backgrounds playing to male fantasies and it can get a bit boring.
There's not a lot that I would change with this photo with just one exception. As you look at the photograph you cannot help but feel the girl looks rather yellow.
If this were my photo I would be inclined to select all the skin tones and then use the Color Balance tool to remove some of the red and yellow from the midtones. In doing this the skintones will take on a more normal appearance while giving the background an even more striking appearance.
Cheers for now, Anthony
