Back to nature

Various render tests of an old model of a destroyed aerotrain.
As it is my first scene from scratch in Blender, I mainly wanted to learn about rendering, lighting, and get a deeper understanding of both Skysim and Graswald plug-ins. Some pictures have the native volumetric clouds from Skysim, other ones have .vdb clouds. These render much faster.
The first picture has been post worked in Krita.
