Like what you’re trying to do, the colours and penetrating stare of the model. Keep trying to imagine the image with a touch more space on left and above so she doesn’t feel quite so squashed in the corner. Maybe even with a touch off the bottom.

I also would love to see some more negative space. But such great complementary colors. It is really nice to look at! Not too keen on the make-up. She would be more beautiful in a more natural look I think.
