Thanks for the comments.
This was actually built in ADT (Architectural Desktop) as a BIM model. I used SU to create renderings, animations, and shadow study for presentation purposes.
I turned off the edge display on the main facade rendering because there are so many unwanted lines showing that I didn't have time to clean them up (a drawback with importing models from a different program, they won't be as clean as being built directly in SU). I gave the trees slightly different scales but I guess I would need to rotate them to give further variation as you suggested.
The time to build the model is hard to tell, as the design has been changed so many times.
The time in SU is actually not very much, once I have all the entourages in place and the scenes setup, it's just the matter of reimport the updated model or portion of it, export the images, then sit and hope the computer won't crash.
Thanks again. Other works I see here are fabulous.
