I don't see much. If you're talking about the pink fringe of the girl's skirt, just change everything to black in the texture editor. Also, I think your concerned that the sun's position on the horizon does not correspond with their shadows. To fix this, follow the instructions on the above picture. Sorry that I could not show a blank scene where there is a horizon to see, but I was in the middle of a render. Anyway, hope this helped.
