Unlike Eko Dev, I don't really like the mix of 2D and 3D. I'd say stick to one (so of course this is personal taste).
I'd also change the two pillars you have on the side to rendered 3D images, rather than 2D.
I found the perspective odd - the buildings are taller than the trees but it appears to be single-storey buildings.
You can also break-up your night sky by including some clouds.
