No worries. I know it’s tough to ask for feedback sometimes, but you’re definitely getting there. Adding uneven-ness to the asphalt texture via a multiplied composite material and small things like that always help a ton. Also, spending more time in post-production will pay off dividends.
I’ve tried to capture the mood a bit better and bring small touches of life to the render. I used photoshop for 15m and drew masks quickly.
I completely understand that most clients don’t really want the type of result I’ve provided. I have had those clients to, but you asked for advice to make exteriors more “photo realistic” so that was my mantra when photoshopping.
Major points I did:
1. Separated the background trees from the foreground (levels, drag up the black point at the botton to lessen the contrast of far away things), with this sort of weather there are a lot of water particles in the air that light will reflect off of and lessen contrast quickly the farther away you are.
2. Add small details of water, and a new asphalt texture, to better reflect the environment
3. lots of small color corrections, I referenced this image: http://2.bp.blogspot.com/-KxcCEKzpWNk/U1ORNTHRrBI/AAAAAAAAKB8/zNcykP3SJjk/s1600/DSC\_0029.jpg
to see the overall colors, the nature of the photo is low contrast, no directional light, lots of cyans. I added some procedural photoshop clouds and broke up the hues of the brick texture as well.
