It's seem that the focus was not made on the eyes.
And try to crop, I think theres a too big space between the head and the end of the picture. Keep working!
You found a corner with nice, even lighting and the pose is good.
I don't know to what stage you planned this shot, but if you want viewers to concentrate on her face, put her in a less busy shirt - and perhaps long sleeves.
Aw dang, I actually had this picture cropped, I posted the wrong one. Thank you. I never thought about long sleeves, I'm new to this, but I have been reading a lot. Thank you guys!
