Your site is near perfection.
1. The green "partition" at the bottom spoils your site. Remove it and bring up the footer image to complete the site.
2. The menu links have matrix brackets surrounding them. I find that these are often misused, and such are yours. These types of brackets should never be used on a site, unless it is Flash and the brackets are animated. Simply getting rid of them and keeping all the links the same format would benefit your site.
3. Don't worry about the size. It is the content within it that matters and the way that content is provided. The narrowness of your site looks the ideal. If it was say 600px or wider, then it would just look stupid.
4. The stars around the first letter of the title images are a little warped. If you could make them anti-aliased and a little smaller (so that they barely surround the first letter) I think it would look a lot better.
5. If you look carefull at the man holding the trophy, there is a slight bit of that picture protruding out of the frame (and I don't mean his arm). A small line of pixels (roughly 2px) of the landscape behind him is showing.
6. You into is perfect. It is not the same boring intro as everyone else's, "Hello and welcome to my site. The exits are located here, here and here..." Great job on making it different.
7. Normally a header image should always have the main content of it on the left, however when the site is as narrow as yours, a lot of rules get thrown out. Especially that one. I think that it looks perfect and should NEVER be changed.
8.

The below image takes up too much room on your blog entry. Your site is simply too narrow to have something like that in the blog. Provide a much more effective:space title to bring out the content better.
9. The title bar of your blog entry does not fully connect to the surrounding border of the main content of the blog. This may however be an indescrepancy with IE, but please check it out.
10. The copyright on your site is good. However, remember that it is not LEGALLY BINDING. This means that if anyone does decide to copy your content, you can not sue them. It would also be a suggestion to put in Copyright(c) 2005, YOUR NAME. That way we know who it is copyrighted to.
