I sketch cute characters on my Moleskine notebook, then I use Blender to create the characters in 3D. I use Blender for modeling, shading, lighting and rendering.
The materials are plain colors with different values of roughness/metallic. I use a shadow catcher for the shadow on the floor and the compositor to add the backgorund color.
This Vol. II "The last of a dying breed" is dedicated to supports that are no longer used: floppy disks, compact cassettes, vhs tapes and so on.
