So there's a site called 99 Designs, were anyone and everyone can look for a designer... or a designer can look for a contest. There's one for a website called practical e-commerce (as you can tell from the image, obviously). Thought I'd start uploading here as well, just because I'm in need of much feedback so that I can improve.

Go nuts, don't feel obliged to be nice... comment away both good and bad. I need to work on refining my work for a professional environment.
