Wow I feel like i’m looking through a bad camera lens. I personally think there is too much chromatic aberration and the overall scene is too bright. Turn down the light source intensity a bit, or at least darken those tiles or the stucco. The architecture is very nice though, and it looks like you got your lightmaps right.
The grass could easily be made more realistically with the assets in the free “Kite Demo” pack on the marketplace. Paint the field grass asset over the current grass and you’ll have a nice 3d looking lawn.
One other small criticism would be that the scene feels very empty, and this is very common in outdoor achviz projects, people just don’t think about the background or what’s beyond. If you just put some trees behind the fence or something like that to tell the viewer that they are actually in the real world, not an empty level. Nice work though.
