The only thing that keeps me from saying that this is a totally excellent picture is the strong, large shadow of the nose. I can imagine it would not be easy to aim another light just at that particular spot on her face, but... if only that shadow wasn't so pointy. I hardly dare to suggest this, but perhaps some more PSP would solve it?
I love the blue tone. I love the hair shadow that's running across her eye. I love her expression - the look in her eyes, the parted lips. Nose shadow nothwithstanding, into my favourites it goes.
