Photo 1: Too much destruction. Should focus/zoom in in one particular subject and eliminate the others.
Reflection on the wind screen should be avoid.
Photo 2: Composition problem. The ratio of the wall, windows and the walking path (drain cover) is not in proportional. The reflection on the glass also have to avoid unless there is something special you want to show.
Photo 3: Generally, it is good and the ideal is clear.
Photo 4: Good composition, but if shoot from a lower angle, It will be better. If possible, try to impose a BOKEH on the background. (Switch to macro mode and shoot in longest tele)
