As others have pointed out, the menu should be re-done. I actually don’t bother with the commas (one could argue that they are part of the design) but the menu is hardly noticable as a menu. At first glance, it just looks like some additional catch-line.
The fact that the text uses the whole screen width makes it hard to read on anything but a 4:3 monitor IMHO, because you constantly have to move your eyes from the far left to the far right to read it.
Also get rid of this grainy background texture and replace it by a solid colored one.
And some basic SEO hints:
Give the title-tag a little more content. You already have different title-tags for the different pages, which is good. Just add some additional stuff to it.
Add a meta-description to each page that briefly describes the page’s content.
You are already using h2-tags. Try to give each page one h1-tag in addition with some descriptive text in it.
Don’t use images as text, use text. Whatever looks like text on a webpage should be text, not an image.
