I think your lighting is well done, but the pose is wrong. Her eyes look disembodied and a little unreal. I think moving you (or her) back about 20 degrees or so towards center would work better.
The biggest problem for me is the highlight in the ear when the rest of that side of her head is in soft shadow.
Her head is turned enough so that her eyes not right either.
Pretty model, nice light, good "connection" with engaging eye expression.
Much, much, better than most would make.
Is there anything I saw that might take a little correction or different approach?
1. The skin tone and color of lips looks a little "off color" to me. I am not sure why, but it appears a little "cool" to me (not warm enough).
2. The eyes do not bother me with their position. They look "natural" to me at the direction to the viewer. The only thing that keeps them from being "perfect" is the bit of hair that crosses the iris in the near eye.
But...those are somewhat minor points. Overall, I think you did make a nice image of a very pretty model.
You are going to need a larger light source or you can move your light source closer. Judging by the catchlight the light source is far away. Also, a soft rim light would be more flattering as it would bring out the neck/face hair.
