City by the sea, 2011 - 10 second pen-on-paper sketch. I later filled in some of the areas with color. No, I did not use adobe illustrator.
City By the Sea II - Just experimenting with changing shape and gesture midway though the line, going from rectilinear to curvy.
Abstract 9 - Just having fun. I drew this freehand with a black pen, then imported into photoshop and filled it blue. This could be either a rug patten, wall art, or a T-shirt.
Fruit Loops, 2002 - Quick sketch, then scanned, then traced in adobe illustrator, then imported into adobe photoshop and filled.
