It really depends what plan you're on. As far as I'm concerned (and don't quote me on this) x10Static requires no ads, x10Advanced requires textlinks, and x10Corporate requires a Banner ad.
Like the other guys have said, its a good start. I like the fact that you've used curved rectangular corners. However, the very few colors on your page are not extremely appealing, and they quickly make the person 'bored' in a sense. If you're targeting a "simplistic" audience, then your nearly half way there. If you're targeting a majority of "sophisticated, colour-freaks" then your far from half way.
Ah, now I see how your doing rounded corners. Not by CSS (which I believe is more supported over all internet browsers), but by javascript...
If would like a look at a website I made using CSS from scratch (Yes, just a white background and some black text), then just PM me.
