Hi Jeff,
I don't consider myself an ArchViz guru, so I'll keep my crits a bit more general.
First is figures, I always find a scene without people in it is a little bit desolate. My personal favourite is the black transparent silhouette.
Second is the sky, it looks a little like the render is incomplete, so adding a sky image would really help a lot!
And lastly is the styles. You've super imposed the render over a photo, that is, the real with the unreal. Try get some consistency, perhaps just do basic form models for context builds and roads & just render them white or some neutral colour for a bit of stylistic consistency! Modelling the roads and basic cubes for context buildings doesn't take long & will save you from trying to get the render on the same angle as the photo. Additionally, it will also give you the freedom to render from whichever angle you want!
Hope this helps!
