New to Blender, just started about 4 months ago. Have always wanted to learn 3D modeling in my spare time.
I actually have found it most useful to build 3D concepts for use in work-related powerpoint presentations (vs drawing 2D shapes in powerpoint). Takes longer but a much bigger impact.
My work (as amateurish as it is) can be seen here: https://new23d.artstation.com/
