Wow
What a good use of color in those eyes, the eyes remind me of my girl...the saturated deep bright green. The hair color and line work is good and the shades and shadows in the hair work well..i like the body position and slight head tilt. I would maybe give a background here since the white is a good focus for the girl but the background would add a more scenic element

Just maybe a background and less white for a scene
