1. Your html doesnt validate :shrug:
2. Not SEO.
3. An image map for top level navigation? Umm, ok, but a list would be better.
4. the artwork on the home page should also be a list.
5. The post-it note would look better with icons.
6. Your webdesign.html needs more formatting. Looks boring.
7. Your web design sited dont appear to be done. Your Zen site's css isnt linked correctly.
8. The client doesnt care how your workstation looks.
9. The home page look empty. Needs more stuff.
I think you are headed in the right direction, you just need more of what you're doing, and more formatting of content.
