It works very well for me, the gloom was a good one, because i cant see any urban things with color in this building, very nice details, very nice composition, bro what camera are you using and what settings?
Is this building somewhere near Outram MRT? The building looks straight, which is not easy to capture unless you have a high view-point. And where you shooting from?
Anyway, I kinda like this pic. I think you should change this title instead.
For my case when shooting buildings, I like to show light & shadow to it. This will make it more 3D in a sence. Do include people in it too (if there is).
Do try more different mood to it. Even can shoot if there's light rain, evening or night scene to this building too.
Hope you have fun experimenting. Cheers dude.
