You've handled the technology well, but as Shingo says, more ground texture would help. Some texture should be on all non-reflective surfaces like the stucco. You do this with the displacement shader - roughness .01
Overall, it seems quite dull. What rendering engine?
I think that many rendering problems are eliminated by composition. If you get drama and depth, you get viewer engagement. Who cares if it is technically excellent or not if viewers can project themselves into the scene?
I've stretched it a little in photoshop and cropped it to delight the eye. And added noise to soften smooth building faces.
Where's the door? When you render without presenting an obvious path for the eye, it becomes a barrier to engagement.
Nice uplight on the soffits - that is usually a newbie problem. How?
