I agree Bobblehat. But she's also cold, calculating, aloof, uninterested and completely unemotional. 42 sets, 6,153 images and she hasn't 'popped' once. No interest in the photographers Voronin and Leonardo, the people she's working with, her surroundings or the work on hand.
In defence of Olga, that could be a problem with the photographers. Neither shot close-ups, headshots or bust. And both like to get up-close and personal with their models. Both used long lenses, full length, full frame shots. And generally that's at the request of the model because of some defect or skin blemish. (I didn't notice any of either).
So after all that, the ball is back with Olga. She just doesn't want to get too involved with the shoots she attending. Probably why Voronin gave up after 33 sets.
Gorgeous girl, love those full lips and what a great body, beautiful.
