Make the title space smaller, remove the "welcome to..." message - people know they're at your website.

Use text links with a background image for the menu on the left - if someone has a default text size that they browse in that's larger than the average person's, then they're not going to be able to read your links.

Ditch the background behind text - it muddles everything.

You have some content that's left-justified and some that's centered. It looks weird.

On the plus side, I like the way you put the 4 most-visited sections in the center of the homepage.

DO NOT USE FLASH. Not because of what Ake said on the amount of users that don;'t have the plugin (97% of users have flash), but he's right on about usability.

Also if you look into some templates, you'll probably find something you like for not that much money.
