Beautiful! Her makeup and hair look amazing! I love the lighting and the focus is great, but I also think it could use a bit more saturation. I just don't feel that the amount of desaturation is flattering to her.
Besides the praise that's already been given I'll say the skin tones are very nice, imo, nothing blown out but some nice contrast. I'd be interested in knowing your light setup/arrangement if you are interested in sharing it.
All that's been said is true, but the shot is ruined for me by that dark thing in front of her shoulder, which I assume are her legs and knee (?). It doesn't belong there (an alien presence) and is inconsistent with the elegance of the shot.
I agree with Murray, this is a BEAUTIFUL shot of a very lovely young lady but I spent the 1st 30 seconds looking at it and wondering what that blue thing was.
I thought it was a jacket--like she was cold and covering her bare arms with it.
This looks like a fashion shot to me. So, the knee thing would depend a lot on what is being marketed. If its hair product, than you're fine. Her hair looks amazing.
