Very nice site; I like the layout - maybe revamp your top banner though. The purple text doesn't really match the rest of the tone.
maybe make the banner a little shorter too, it takes up too much space and the letters are a little blury..
Nice website with amazing color combination and powerful content. I really like your beautiful website.
Few pointers 1. Have a logo 2. Reduce the number of top links 3. Shorten the content on the home page.
