Here is some tips and "rules" I suggest you should change:
* You have 805 pixels as width on the page, that will force the users with 800x600 resolution to have a horizontal scroll. Change to 770 pixels instead.
* Don't use frames, use a table or div/css design instead.
* Don't use the same background on the "site" and the whole page. (hard to explain, but where you have the text, use another background color there)
* Get a cooler header image, look in our tutorial archive to find some cool effects.
* Use another font in the text in the header, it looked pixlish.
And I like the colors you have choosed, they're nice

Keep working on the site, a website is never finished, always under construction all sites can always be better, nobody is perfect.
