hey vv. some nice detail shots in there. i really like the symmetry and parallels on 7 and 8.
i think with your building shots you are perspective correcting a little too much, they are actually starting to look bloated, which can look even wore than converging. if you are having that trouble, fix as much of convergence as you can without distorting too much. if its a bit converging i think that will look better than bloated.
