1. Adding more pictures of the actual app would greatly increase credibility of the website. Right now the website doesn't even look like it's done. It is greatly lacking in content. Users want to see what they will be joining before they join.
2. I would suggest using better panoramic pictures for the rotating banner. It looks stretched out and pixelated. With the current content, I would consider condensing the whole website into one page.
Good stuff. You just missed out the free reviews but you can always order a review (http://sitesesh.com), and with a coupon code, it goes down to $8 :)
1. Great overall first impression! Lovely logo, banner, and custom made images! The sections are spaced evenly and the content was well thought out.
2. I would make the "Live Demo" link (the one in the middle), into a button and make it more appealing. It was losing attention next to the other well designed sections.
3. Consider using a different image for the other sections.
