Hi
I like that are you doing - but have to say design looks to be "very minimalistic" (but probably 'cause i'm using FireFox)
It's hard to get that Main Menu is pop-up... Also, at some pages I was unable to click by Prices & Orders (you have to move mouse over title and search for "magic" pixel to enable this menu option
So, you need to use your art experience and upgrade website. Otherwise, many customers wouldn't be able to find you really nice graphics
