Architecture visualization

This scene is for a client. I cannot change the project and the environment should look like a ranch with only these 2 trees nearby.

biggest note is that the car looks like a billboard (how does it get there? needs tracks)

Looks good. In addition to the others’ comments, I think the foreground grasses (on the right) should be made lower or even go away enough so they are not blocking the patio. Your depiction is probably more realistic, but the client will care more about seeing the building/patio more than the plants.
