Greetings from the Critique Club. This building is very interesting with very cool textures and angles - I can't help, however, thinking you might have chosen a different angle that would show off the building's architecture better. This flat angle just doesn't seem to do the building justice. Also the sky - an old photographer saying is "seen one blue sky, you've seen em all" - meaning a blank flat sky is fairly uninteresting. For overall improvement of this shot, I would suggest, besides the change of view-point, either waiting for an interesting sky, or composing the shot to not include the sky - or very little of it.
These comments are meant to be helpful, I hope you find them so.
Good luck
