Hope you don't mind but I had a quick go in photoshop with it. I have increased the contrast, added a vignette, sharpen etc.
I find the 30D does suffer a bit with noise. I have been told that there is a great piece of software called noise ninja which works quite well during post processing.
I have spent some money on getting some fast glass, which means I can try and keep the iso as low as I can, which has improved my photographic results over upgrading the 30D to a body with better iso performance.
