I like this, the shadows on the building, the evening, peace of mind, quiet time, time for self. Those are the thoughts that come to my mind when looking at this.
Portrait ? no.... people pic ? yes.... good image ? absolutely... movies poster or CD cover or ad shot....very cool Marty very moody and nice light.....it will be a good frame once you trim off a bit of the top and bottom...like the black edging but you got a bit to much...start with a speck of shadow just below the step and from the top take off half as much as the bottom crop....
