These are a small fraction of illustrations that I did for a project at FableVision Studios. They ended up as tiny thumbnails about 1.5" x 2", but I worked on them at a much larger scale.
From top to bottom:
Biker in Snow
A Pipe Shop (to which I added a couple extra elements for fun - Mario and Luigi)
Crab and Clam
Aztec Basketball (Apparently where basketball originated)
