Hi,
Its a nice shot, but it really would benefit from a couple of things.
1. I know he's her brother, but he really disctracts from the picture of her and I think this would benefit if he went from the photo
2. Its a shame about the harsh shadows on her face and shoulders- they do detract from the overall picture and she looks to be squinting - although I can't tell if its her smile or the sun.
Cheers
Hugh
