could the retaining walls that separate the patio from the driveway & yard be added?
----------------------
REVISION 2: thanks for adding the patio & walls. there's something a bit odd though- it looks like they're drawn from a different perspective than the rest of the house. is there any way to make this look more consistent with the rest of the house? if you could make the northwest wall angled (like seen in the pic above) that would be great too.
-------------------REVISION 3
maybe i'm not looking at the latest revision, but the render i see still has a wonky perspective, and the northwest corner is still 90 degrees. why is the north patio wall not parallel with anything on the building? if you can't get this looking plausible, please remove the patio/patio walls, and extend the sidewalk to the building.
