Svetlana

Nice composition and great lighting. The skin tones look a bit artificial, at least on my screen. Congrats.

Vladimir,

Svetlana is a pretty girl. The background is nicely neutral. You have a good amount of room around her. Her make-up looks very good.

She is not as sharp as she should be. Make sure her eyes are in critical focus.

Her skin tone has a reddish yellow tint to it and she is underexposed. Notice that the whites of her eyes are not white.

She has catch lights, but they should be more dominant.

It is generally best not to point an elbow (or knee) at the camera.

You do not want the shadow from her right arm to cut across her right eye.

It is generally best not to shoot bare armpits or crotches. Either can look rather tacky.

The lighting and her pose makes her right thigh look quite large. A more slimming pose and lighting would work better.

Your have either tilted the camera or the picture. The odd looking stool is not straight. Unless you have a reason to tilt it, it should be straight.

A hair or backlight would help to make her hair stand out from the background better.

Nice shot,

Mark
