one of my hobbies is rc car racing. it's a great hands on, social, competitive and interesting hobby. I volunteered to create promotional race fliers for my local track. here are the first three.
Here are the first few attempts at drawing with sketchbook pro mobile on my ipod touch. Unfortunately, it is a first generation ipod touch and the software is a bit laggy. It is useable, but not fun :( For now, I still carry a small sketchbook :)
