Second one feels more unified. In the first one, the ground and flask (?) and the two old spar poles, and the corrugated roofing off to the left, those various elements, plus the chain link fencing and the brick street, all of that stuff forms a sort of "street and environment" part of the shot, and then there are the stairs; in shot #1 there is no central theme except "urban exterior". In the second shot, the colorful wall and the shadows on the wall, plus the stairs and shadows are the main focus...it has TWO things that dominate. As others have said, different time of day would change the shadows, and the shadows are a big part of #2.
