A large amount of your text is on images. Search engines have difficulty indexing that and it may harm your position in SERPs.
Ultimately your site is a giant funnel. You want it to catch as much traffic as possible and send it all to the same place - the order form. In light of that, I feel as though your site has too many interesting links that distract the user from ultimately making it to the order form. In other words, you have lots of content, but that content isn't pushing me towards the order form.
Good work, though, I can tell you've put a lot of effort into it.
