The actual drawing is honestly very well drawn, but the character looks too stiff, you might want to make the body more relaxed. You also might want to double check your drawing, she's missing her eyebrow. It would be nice to see at least some of her eyebrow above that one eye of hers. For the clavicle, they are too low, and they aren't really 'straight' lines. As for the background, you may add some detail to it, to make it look more spontaneous, other than that white blob in the corner. Also, you might want to add a signature next to her, or somewhere in the drawing to show that you really did draw it yourself. Other wise, power to you!
