The axes were made with inflate image, while the new 4.0 feature drop to surface was very usefull placing the belts and studs correctly.
The images here use Depth and Ambient Occlusion that can be generated in 4.0 when you save a screenshot from Curvy, they help to bring out the depth of a model. It is worth noting that in 3.0 I would bake ambient occlusion and also paint in textures with extra shadows. But wih this scene I let the screenshot AO do all the work!
