Sorry to bring this up but I feel I owe you to be honest, the skin looks very overprocessed, she looks like a plastic doll and not a real person and what a shame, she looks very attractive and a couple of blemishes only give her character wich is what I feel is missing in this picture. Nice lighting.
I think the overall lighting is good as well as the composition.
But the over use of a NI-like technique and the erasing of every single wrinkle as completely ruined this image for me. Portraiture isn't about smoothe, plastic skin, but about capturing the essence of a person.
Beuatiful blue eyes. The skin is a little too soft for my taste, but that is a personal preference. I think I would prefer it short lit (with the main light on the side of the face away from the camera). I like the composition, although I might have left a little more room below her, showing a little more of her shoulders. Very nicely done and a lovely model.
Probably too much Neat Image here...the blue eye on the right is a little too much in shadow, so perhaps a different pose would have bought out those blue eyes of this beautiful lady a lot more...nice work though
