I don't do architectural shots like this, Phil, so I'll limit myself to a couple of PP things.
Strictly opinion: I'd prefer the strong vertical line at the corner of the building to be perfectly vertical, and I'd like more contrast- although admittedly I'm a contrast freak .

Thanks for the comments Charlie and Tim, I picked up a 20mm 2.8 and was kind of experimenting with it, actually I am returning the lens, its way soft stepped down for my taste
