This is a pretty hard site considering the vast amount of content your are trying to fit in. Overall I think it works well. My only problem is that it doesn't seem to lead me through the page with any sort of hierarchy. I would really try and grab people attention in the places that you want them to look. Right now there are so many things screaming for my attention but nothing grabs my because they all have the same level of Hierarchy.
but nothing demands my attention but the first large image. You have tabs for a few of the sections already, can you move that info from the first page and let it rest on its own? Very organized, just needs something to draw attention to different headlines.
I think this is a good concept. The only thing is that for me, there is too much text on the homepage. Thats pretty much the only critic I have. I like the orbs background.
