A Cinema 4D scene, done for training. There is only the rendering available here (no source file).
Credits for the tree go to Klaus Büchner’s wonderful Tree Plugin. The handsome Bavarian Guy (traditional Allgau Alps costume!) is a low-poly test model (paid work) that I ordered from the fine guys at be3dmodel (Hong Kong) in 2011 (originally intended to go into a game that never got realized. Thought I could put that model to use in some manner anyway).
The “device/box” is sort of a control unit for large combustion engines – it made a nice training object with that connectors and stuff (also, somewhat different to all that guns ‘n cars a modelling beginner usually starts with…)
