Yup its getting there. I'd really watch that shadow pass, as you've got a very black building on the right there. Perhaps do a different light pass for the shads only so they are coming in from one direction perhaps from the right (just a thought) use raytraced shads with a directional light and try the settings for the shadows on Light Angle 20 and the Shadow Rays at 10 or 15.

It may look better for this with one side of the image slightly in shade too.

Ps. Render a Z depth pass too for distance and fog effect. This will give the whole image more scale. This pass is usually set to multiply in PS and then what I do is invert it.
