Which one do you guys think???

In the first image, i am trying to make the new texture part of the existing... it still looks like montage though... any ideas how to make it more real? in the second one i desaturated the existing city which i think relates back to my previous site plans/renders, where the existing city is less saturated... or should i just leave it as it is??.... more realistic (in the first shot) what do you guys think?
