Another oldie but goodie... I completed this in about 30 minutes for a student's sketchbook back in 2004.

Everyone else had drawn characters so I decided to buck the trend and draw a tricked out post-apocalyptic chopper complete with a jousting lance and pounded metal skull welded to the front fender.

The blurred terrain beneath the bike was added in Photoshop.

Also, notice the photos on the right? Those are from my afore-mentioned Flickr account. Thanks to Travis for tweaking the code!

Check back soon for more lost sketches.
