Firstly, I should say that I look forward to seeing your work as much as I do Andrei's work at vishstudio. Yet again you have found a really well proportioned and toned model. My only concern with these 3 images of Patrick is with certain areas of 'whiteout' where the line between the rather light vignette background and body disappears slightly. As a result, the outline of the body is not as defined as it could be. A slightly darker background would prevent this and also give the image the deeper and 'richer' feel like so many of your other images have.
I don't normally pay much attention to colour, as I convert most images I work from to greyscale, so I may be talking out of my backside when I say that the upper chest and legs appear to have more of a blue tint than his stomach - which has a hint of suntan colour. This could be an illusion caused by the light vignette background, but it creates a a colder, clinical feel to the image. That said, I still love it, would still want to draw it, and can't wait to see more images of Patrick!
