Villa : outdoor scene in cyles

Hi all!

1st outdoor scene with cycles.
2000samples , 15mins.

If you have any advice to make it look more photorealistic, PLEASE let me know! (especially with render settings or post pro with GIMP )

(the car in the garage has been downloaded)



I like the lighting and editing however the sense of scale is off, the textures for the concrete walls should be smaller and I think the car is slightly too large as well.

Also for the architectural standpoint, is the “house” just a glass-framed kitchen with a pool and garage?
