A competition image for Patalab architects, this involved a quick turn around of 2 or 3 days. The basic building and landscape was modelled in Maya and rendered with Mental Ray. Then came plenty of Photoshop work, including all planting composited from site photography and other landscapes shot specifically for this image.
Looks like they have suceeded in wining the project so a job well done!
C&C welcome.
