Maybe this is not the answer you were expecting, but I would start asking what else this landing Page don't need?
A landing should be designed around one (and only one) actionable goal. What do you want to acomplish? Sign ups? Traffic for another site?
Are all the elements (visual & copy) aligned with your goal? Do the landing convey the message that you want your visitors to understand?
I think you are doing a really good job, but need to focus in asking different questions.
