I can't really get a lot from this one Dave, sorry. The lighting is very flat which isn't helping the fact that the model is pretty flat too! Her hand in that position doesn't really achieve anything. It looks like an uncomfortable attempt to cover her left nipple and her forearm flat across an already pretty flat chest is reducing her 'feminine curves' such as they are. I don't mean that in any way disrespectfully but she has quite a boyish look anyway with the short hair, etc and this isn't helped much by her twisting virtually 90 degrees from the hips upwards.
I am sure you have other shots from this shoot which do Suz a lot more justice than I feel this one does. Apart from the slight shadow under the right eye that Skip has mentioned, she has a much stronger shadow to the right of her nose which is not very flattering.
You've taken a lot better and I am guessing you took better in this shoot
Cheers,
Rob
