If I can be a bit picky, the arm just off the shoulder is blown out too much which bothers me and the bracelets almost distract me from her beautiful face but love the details in the eyelashes and other small areas as well. She loved posing for you. The few loose hairs in her face could have been moved before the shot. After looking at it a bit longer, the lighting on the hair on her right side almost make the hair look grayish. She doesn't look old enough to have gray hair. Very beautiful woman and very good pose for her. I bet her eyes are stunning.
This is a beautiful shot. Love it. Nice tight crop. But there's something "off"... can't put my finger on i t. I will come back... perhaps my next comment will be more insightful or inspiring... or something. lol
