I have two issues with this image and while the subject is pretty well lit, the pose makes it appear if she is supporting her head with her left hand, presumably, and I am just speculating, to keep her from sliding out of the frame because of the pronounced slant to the horizon. I critique this because I think there is great potential to your shooting but it's the little things like this that will keep you off the winner's podium.
Next time, check that horizon line and then have her do something with that arm and hand that makes sense...pull some more hair off her left side and let her hand either slide through the strands or be pulling a strand up whimsically, but something other than as a head prop.
Cheers.
