Like some of the other folks on here said, try changing your focal length and if that doesn't work then I'd try making some more precise pinholes. Personally, I was AMAZED when I started using my home made pinhole's. I could not believe how ridiculously sharp they were for being home made. I make my pinholes with sanded down aluminum from soda cans and sewing needles. Anyway, that's why I found your "blurry and uninteresting" comment a little strange - because if I can do it, anyone can Try checking out http://mrpinhole.com/ if you haven't already. The site is nice because it will tell you how long your focal length has to be in order to cover a certain size (like 4x5 or 8x10).
