Futur - Futuristic cityscapeproject?

I’ve recently started using blender a bit more than before.. and for couple days I’ve been working on a futuristic(ish) city (or small city for now)

First, couple pics;

I’ve been working on it for couple days now, and it does lack some detail.. and the buildings have been only copypasted around and so on.. The thing I have focused on though, is the lighting. 

So, give me yer thoughts, I’ll be working on this at least for some amount of time !
