Looks really nice, I really like the layout. A couple suggestions (keep in mind that though I may seem a little harsh, I'm just trying to give you my honest opinions):
- You might try changing the links on the top to rollover images, to make them stand out. Out of convention, people are used to having links change color when rolled over.
- The sponsors page is too long, it should be divided up into 2, maybe 3 pages. Its a lot of sponsors, something I wish we had, but with that comes a lot of scrolling.
- Consistency with the links (especially on the sponsors page). I like the headers being orange on the rest of the site, but you need to distinguish which headers are links and which are not.
Overall, I think its a great layout, not too busy, good color scheme, good menu system. Once you get the content up, you should be in the running for a website award.
