Glad to see you're branching out and trying new things instead of the standard header, body, footer layout. The layout is good, solid, unique. The only thing I'd suggest needs adjusting is the body background colors. You're working with four _basically_ four different shades of brown. That's just disgusting and boring looking. Try to limit it to two, three colors tops and make them distinct colors. using a brown is fine, but don't use it twice (changing the value doesn't change the color).

Overally, looks good. I commend you on the work so far.
