Nature. the shadows of the big mountains on the side, reflect on the small mountains in the foreground, and highlighting the mountains that lay behind them. the red mountains form some sort of a margin that portraits the mountains in the background. the light use is amazing.
I believe that the photographer did a great job by placing the model on the side of the picture, rather than in the middle. Her position makes the stairs look like a journey she doesn't want to go through. The model's body language speaks disappointment and beauty.
a few of the objects in this picture are actually the same size. but the way the photographer set them up, and the angle he chose makes it appear that some are smaller than the other. he also has only 2 or 3 objects in focus and he left all the other objects out of focus which also gives the audience a feeling that the objects aren not really the same size.
This picture is very simple and very straight forward. the photographer actually used the camera to magnify the inside of the cigarette, giving it a completely different and strange look. i love it because it would take you a few seconds to actually know what is the object that is photographed.
