I really have to say that the background that you have on there takes the attention away from the meaning of the site and directs it straight to the bg. Plus, the bg colors and design is not consistent with the rest of the site. It looks as if it was just placed there.
You are going in the right direction with the website. I would suggest changing the background to a light gray or so. That will contrast with the rest of the site colors.

Same as above, thanks for re-confirming the need to change the background. I will give your suggestion a try and upload a new preview for you and others in a few minutes.
