This drawing illustrates different materials, sectioned like that of a basketball. Hopefully you can tell, but they are: chrome, red glossy plastic, clear acrylic, stainless steel, wood, and carbon fiber.

Digital Illustrations Collection

This is a collection of drawings from Digital Drawing class taken while at AAU.
I started by sketching by hand, before switching to my tablet. I cleaned up the sketches using SkethBook Pro and SketchBook Designer. The drawings were finished up/rendered in SketchBook Designer and/or Photoshop.
