#1 is just to crazy for me, but the texturing is good. Love the windmills though
#2 Is really "corporate", nice buildings, horrifying at street level though.
#3 is well modeled but to funky again
#4 Isnt really modeled well, but it made exellent use of the edges. Nice desighn overall.

I dont get the concept of big trees on skyscrapers, the root system for a well taken care of oak tree is huge, you would bassicly have to fill a swimming pool with soil and dirt for it to grow. And when it dies that kinda sucks for you. Little vegetable gardens and stuff could work though.
