Really nice images!
This house is quite similar to the type of architecture I work with often.
Can you provide more detail about how you executed the lawn and the other landscape elements around the house? Did you model that neighboring house as well for the rendering?
Can you provide more detail about how you executed the lawn - i used Forestpack and grass with iGrass volume
the other landscape elements around the house? - I had the address of the house, I found the house on a google map, the camera went downstairs to the street and I saw everything that is around, having this visual information, I tried to repeat it in 3D Max
Did you model that neighboring house as well for the rendering? - yes
