Colors too soft lacks snap, expecially in the eyes, the light to the right is way to bright, should have been diffused more. Lighting is too flat no separation from the background, and her hand next to her face is causing her hair to buckle. A slight tilt to her head would have helped, beautiful model...
I really like the tone of the colours (like pastel). Maybe i'd prefer it with a less morbid light, sharper image for blue eyes, but that's me (and my terrible english, sorry). Good work anyway!
