This is one where I would wish I had such a new version of PS that I could straighten that lens distortion, as if this photo were taken with a very good, expensive, special camera for architecture photography. This photo could very well do with all straight lines!
And it could do with the corner brightened up just a bit.
Other than that I find both picture AND building as such really nice ... I would have a field day with that building, I think, if only I were close.
