The silhouette of the girl is nice. The ground work is there, But you seemed to have focused on her eyes and hair and rushed or forgot about everything else. I would love to see you get in closer and paint and detail the rest of her. The biggest thing that stands out is the detail on the face next to a hand that has no definition. You could easily added in some quick contrast to suggest definition into the hand. Also the black lines on her lower body are out of place. Maybe at some point revisit this and give it the time it deserves.
