Great work, not even gonna lie. For your first try, you succeeded me by a long shot. (Basterd)
Ima try to give some criticism, so bear with me.
The focal point is centered around the girl's right cheek. What I would do, you don't necessarily have to,
is try to increase the focal point to at least the face area.
Trying to blend white and black - ehh - I don't really like it that much.
Otherwise, you did a great job, no lie.
Composition could be greatly improved, make the focal her eyes, not lips, it's always more effective. Create a light source which draws less attention than the focal. Too little contrast and too much negative space, also try use the rule of thirds effectively for your focal point.
