Landscape cropped portraits work better with eyes following the rule of thirds or more negative space. Also the background is too busy here. Great idea to use the blue jewel with her blue eyes, but the cropping on the bottom does not seem ideal... would be better if there was a blue bubble on the left side of the necklace as well.
A lot of potential here. The background really distracts and the crop of the top of the head bothers me. I really think this could work well. She has a very good look that would translate well into a avant garde portrait.
