My latest work. Tried to incorporate some comments I got in the WIP thread.
Modelled in Blender 2.73, rendered and composited in Cycles. Textures and a little bit of nose removal done in Photoshop.
Characters are loosely based on the old Transformers cartoon.
One note: pannels on the background are modeled by Andrew Price and can be found
