fantastic job on the house, yes, good colour grading, but personally a little more black would be nice as it seems a little faded in parts. The tree leaves in the 2 foreground trees give the scene away. What happens if you remove the 2 front trees altogether? the foreground bush is looking great, much better than the trees. I guess the trees look a little too CG, either by modelling or texturing. Or maybe move the camera in so you do see the trees but still have the shadows?
