I think the eyes are a bit cold for my taste. Try to look for a "natural" reflector, like a buildind or something, to add catchlights into her eyes to opoen them up and make them look a bit warmer:
Her eyes also do not look relaxed, maybe a bit "squinchy." It's better if the model is looking at something very muted and not too bright, so that you get a very relaxed expression, especially in the eyes:
Also, try not to crop across a hand or finger.
All of these examples were shot outdoors with no artificial reflectors or fill flash, just natural light and natural reflectors.
