I like the idea of over-exposing here, yet you may have gone a stop too far...also, without the ability to tweak contrast this doesn't quite work...good shadows and composition
This has potential. Next time try to diffuse the sunlight to avoid the highlight/blownout parts. Fill in the shadows that are that way created with some reflected light or diffused flash. Also don't use a carpet as a background, put more distance between subject and background.
Great positioning of the model, I like it, but the direct sun needs to be blocked in a shot like this. It's simply too harsh. Suggestion - try the same shot, but keep the model completely in the shade.
