Do you type your own HTML or do you use a program? I'll assume program so...

Pros:
+ There is enough contrast between the text and background.
+ I like that you use one font through the page instead of making it a cluttered mess (except that one part...)
+ It is also a good thing that you used one alignment through the page. If you used left, center, and right alignment your page would be confusing.

Cons:
- Personally, I don't like big font sizes. By using the HTML tag for font you're kind of limited to font sizes. To me, 3 is an average size. I'd drop to 2 though I'm not sure how that'd look with your font...
- I'm also not a fan of Comic Sans. It's really your choice though.
- How large is everything for you? I've got a really high resoltuion and your font is STILL massive. Get rid of some of the blank spaces. Try using tables or DIV layers. I suggest tables if you're just starting. If you're using Dreamweaver tables are pretty easy to use.
- Instead of using buttons try text links. With the table you can set it up so the "features" are on one side and the links are on the other. Get what I'm saying? Only two cells.
- Try left aligning things. It's way too long to be centered. With lists it's always a good idea to left align.
- Where are the pictures? There are two ways to keep people interested in your website. The visual appearance and content.
