Hi there!!!
As far as the picture is concerned i'd like to know the setting of it and the goal u'd like to achieve through the picture.
The canvas, namely the skin is perfect.
Therefore, there is not enough contour (more shading needed).
The first thing i have noticed when i looked at the picture were the eyes.
The choice of the look is perfect, a natural smoky-eye look.
Neverhteless, they are not even.
The left side (if u look at the picture) it's less define than the right one (the line along the lower lashes).
The lips are perfect.
U could have mixed it with a bit of orange-pink, just to give extra light to the lips and to the face, making the eyes the focus of the look.
The body is perfect (i do like the skin a lot).
U could have used a strobe just to highlight the beauty of it and make it more natural.
The hair is just great, natural and sophisticated at the same time.
What i do not really like is the way she bends and the position of the arms.
It could be slighty out of place (she is such an elegant woman), loosing all the sensuality and elegance she has.
Futhermore, the picture looks a bit unrealistic.
All things considered, it is a very good picture.
Congratulations,
Schwarz
