I think the general site layout is good overall format, but the design could use a lot more polish.
I would suggest maybe a subtle texture for the background, a tighter color scheme (see http://colorschemedesigner.com/) and sexier typography.
From an e-commerce perspective, I might suggest you put your main product more prominently on the front page with and add to cart button or view more button, instead of the slider.
also, the area below the slider is a bit cramped in my opinion.
