If I'm being completely honest, this design didn't blow me away. While there were one or two pages such as About Advance, which were somewhat interesting, I'm afraid the rest of the site felt pretty standard.

So, while the website does an acceptable job of showcasing your theme's features, I think there is definitely room for a more creative solution here. Especially, since you are targeting marketing firms and creative agencies who tend to look for something more than the standard look and feel.
