Hi Community,
Attached an exterior scene I made for a builder, your c&c are welcomed

A few pointers:
Birds are way out of scale, they look like prehistoric pterodactyls!
The building itself is pretty blown out, try tone it down a little and enhance some of the details with an AO pass.

For a first go it is very good, just work on the little things to enhance your image further.
