Looks like a small amount of camera shake in your image.
It has a somewhat surreal look to it. The dappled lighting on the wall is good, and the mix of color and black and white is interesting. Having him sit in the hallway is good, but the tilted line of the step gives the image a skewered look (unless that was your intention). The focus is a little soft, possibly due to low light and/or him moving when the shot was taken.
Cool!
But I really think you should rotate the pic to get the floor horizontal. As it is, that detail grabs a lot of the attention away from the subject.
