This is a collage made using 3D software (Blender). It is more technical than 2D work but a lot more can be done with it. This is a very simple example using both 3D and 2D elements within the final composition.
This is the software Blender. Takes a bit of getting to grips with but it is worth the effort required.
My workstation. iPad pro on the left (used to make the main image within the final composition) and my main computer with a drawing tablet that I use as a second monitor.
