Feedback request: how can I improve the zen kitchen's site?

I’m gearing up, now that I have a moment to breathe, to revamp the TZK site, and I’m thinking it needs a bit of a re-design; I’ll likely keep the same color scheme, and a few other things are going to stay consistent, but I want to clean it up a bit; maybe move things around. So, in the interest of market research, I’d like to ask you, my humble friends, for your opinions on what works about the current site and how I might improve things in the next version. If you have a moment, I’d love it if you’d take a look and give me your feedback.

The site’s at tzk-design.com; some things I’m definitely thinking about already:

• Keeping the portfolio broken down by client, but changing the way that case studies are displayed to showcase the images more than the text (haven’t quite figured out how that will work yet, but if anyone has a suggestion, it would be appreciated.)
• Changing the navigation to be more clear and text-oriented;
• Breaking up the “fun stuff section” into photography and recipes (I think I can get rid of the stuff I do for fun, since I don’t do enough of it)
• Switching the recipes into a food blog that has recipes and general foodie notes.
• Cutting some of the copy;
• making the sample sheets, resumé and client questionnaire more easily accessible.

Thanks in advance for your help.
