my first post…
You may to improve the perspective 
the rest is so good.
Looks good so far, but watch those verticals.
I think the verticals are pretty good …it matches spot on to the image behind.
Not that I wish to argue with Natty but I think the nearest corner is not straight enough compared to the rest of the building, especially if you compare it to the rear brown brick building. The top of it just seems to lean out.
Just an opinion… 
mmmm … it maybe a tad off … but pretty good in my eye …
Just my two cents:
The dark areas make the image looking too hard. The glass needs more work as well.
sorry naty, but he needs a wider angle.
take a look at the windows deformation when you start looking at them still the 1rst degree to the top one in the .
ah …yes this is true ..
My render image has too much perspective…for dynamic effect,
i tried to fix the photo image of bulilding but it distort too much…that why i leave it like that …anyway thanks for the nice comment easee28 and natty…
next time i will keep in mind,
