The first place I would start in your improvements is the width of the overall page. I usually develop websites for a width of around 995px. Most users have their resolution set to 1024 width these days. If other users have it set higher, that is fine, but for most, the width you have your site forces users to have to scroll to the right. And that is something that most users just won't do for every page. It's gets to be a real pain in the you know what to have to continually scroll right on every page.
Then I would consider using the header area for straight content and asthetics and move that large Tutor thingy down into to body of your page.
I would also consider moving the dropdown menus out of the Tutor thing, and into the header area. That Tutor thing is soooooo big, if you moved the dropdown menus into the header, you could then reduce the size of that Tutor thing by half even. People will still get the idea.
I would also clean up the logo imaging. They could look allot more professional with just a few tweaks.
The way you have your footer area menuing forcing the dropdowns to actually go upward is also a little odd.
My 2 cents.
