I really like the desert theme and the sun behind her. However, sorry but the art just looks completely unnatural and unworkable. Her legs looks like toothpicks. I understand you are attempting to foreshorten them to show depth, but they are so out of proportion with her body as to make her look freakish. Her forward hand has the opposite problem; it is huge and could only get like that due to a very short focal length camera lens, of the type a photographer would never use on a human unless trying to make them look wrong. Additionally she is bent over too far to stay upright with her legs spread like that, never mind use her weapon. In fact, if she tried to throw it, she would either completely fall over backward, run it into the ground, or have to perform a very bizarre spin.
