You probably know that making a beautiful woman look beautiful in a photograph, is not as easy as it seems. This photo was taken with care and consideration and therefore it is a strong one. The monotone colours and the soft light give the scene a simple look - easy on the eye. The pose is revealing, yet the straight look of the model is creating a natural distance. You did a decent job in using the back of the sofa to block the light and thus emphasizing the soft contours of her beautiful body. I could have made a short comment in saying: absolutely gorgeous photograph! But I did not..
This is like the scene where Rose poses for Jack in the movie "Titanic". Forgive me if someone has already noted the same thing. Irina is a vision! The lighting is fantastic and her pose is beautifully elegant and graceful.
