.....The pain that she hides

First of all let me just start by saying that I love your work and your technique is absolutely fantastic.

Your use of lighting and sparkles/smoke is fantastic. As is your over painting work.

My notes:

On her shoulder closest to the window we see that she has a bit of light coming onto the shoulder, this light should also be reflected in her hair near the window.

On the opposite side of her hair you also have a few hairs that are standing out. One almost looks like a black half circle and the other looks like it may have been a line of smoke but it's hard to tell.

I also think the glow (smoke) on the right side of the photograph is a little too bright to be on its own. I probably would have brought more in or not included the tiny line at all.

All that being said, phenomenal work on the outlining, rose, skin, sparkles and lighting. Incredible technique.
