sometimes you need to wait....and sometimes you need to have been there sooner. The sun is underused in this, in needs to have more clout in the shot or not be there at all. From a pure abstract point of view, I would prefer it not there at all as the silver, gray and blue color combo would be fine without it. But You need to have the top left of the building in the frame. It would greatly improve the composition.
the dark side of the building is distracting.. especially with the crop. that top left sky area seems to disturb the composition for me. a tighter crop on the left would have helped. great reflection. good angle. 5
did good with finding right angles. I like this shot. I would have rotated just a bit so that the corner of the building was 100% vertical, but his still works for me 6
