Exterior view

Thank you Kurtlan. Actually I didn't notice that. I'll modify. Thank you once again.:)

Regarding horizontal joints: Something strange is happening in the joints under the right-hand overhang- some circular things show up. Also, joints appear to penetrate window surrounds. Have never seen that, if surrounds are to be stone or cast-stone, would not expect that detail to appear.

It looks better, but I know it can be difficult to get it just right without post production. I find that I have more control and save time on certain projects by adding additional horizon reflections in PS. I also have libraries of grass imagery and would just quickly composite that sliver of foreground grass in PS. I would also try and pull some of the detail out of the shadows at lower left and in the opening at top and bump up the contrast in the lighter areas in PS.

Thank you Chris I tried to add some grass & window glass reflections

The materials and lighting look good. I beleive that some reflection in the glass will help and some better grass (material or post production).
