Pen and Ink drawing of a Harley-Davidson Fatboy, done using Rotring pens. Gone for a slightly "interpretational" look as opposed to out-and-out technical drawing. Also, it's been the best part of 30 years since I last did anything like this, so maybe I'm slightly out of practice? ;)

Each panel represents a stylized red and grayscale representation of architectural highlights from eight locations.
