It looks clean, but I'd add more information on the landing page. The four pictures look as if you're supposed to click on them, but they don't do anything but take up space. Most people have some sort of site intro text or offers on their front page. I'd remove the four pictures in one block and instead welcome the visitors and tell them what the site has to offer.
I'd also either remove the affiliates link or add information there. It's kind of strange when someone has a link that says, "coming soon" when they can just not include the page right now. It makes your site seem as if it's not finished.
