First of all i slightly disagree w the last post. I think most artists are their worst critics, all the ones i know anyway (including myself). Yes, there are a lot of really amazing photos and extremely tough competition. As an artist i also enjoy that. It challenges you to get better and inspires you to do more. If nothing else look at the entries for inspiration. I spent hours just looking at peoples work. There's a wide range from bad to professional. Win or not your work will be seen by the public. That's great for anyone just starting out!
