Here is my participation for the monthly contest of the Facebook group Blender3D France. The theme was Akira so I couldn't resist sorting out some time for once to work on some artwork and to hone my Blender skills on a nice piece.
All made in Blender in a few dozens hours of hard-surface modeling, copy-pasting a lot of pipes and elements before scaling and rotating them and hiding the shame of not connecting parts or having pipes cutting through. The character was made with Human Generator add-on (not the clothes, this is some quick sculpting).
