The landing page has too much useless junk on it. My advice would be that unless it adds to the actual functionality of the page to eliminate any. If you're having problem rate every element on the page on a scale of 1 to 10, 1 being "fluff" and 10 being "must have" and then cut everything that's 9 or less.

Also either hire someone who has an art direction background to layout the page or use a template. And again, more colors aren't better.
