I like that you have your main subject dominating the left half of the frame. The buildings are composed in a leading line that draws us forward to see where this man is destined to walk. There is also the fade from dark tones (the man and building in the forefront) to the light tones (the end of the street, the vanishing point off in the distance). To me it is a subtle nod of mood that signals this man's thoughts or feelings: walking out of dark thoughts/sadness to happier thoughts/carefree. Tis a shame that the street does not go off into the distance for that brick wall muddies the strength of the mood created. Also there is an odd 'halo' sharpened effect that is most visible around the dark outline of the pants.
