That is a very sharp picture. Just shows that worrying a little about the detail can really bring a huge difference. I was reading a how to a guy posted on a photo blog on making a pinhole cap for a d!g!t@1 camera. He explined pinhole cameras as "a camera that uses a small hole instead of a lens to make a blurry picture for artsy purposes". The sampes he showed were blurry, but not artsy...
