Congratulations on your new site!
As Brandon mentioned, there is definitely a big problem with the appearance of your text, and you will want to do some cross browser compatibility testing.
The fact that the site doesn`t immediately read as an e-commerce shop is both good and bad... while it is great to have a nice clean interface, at the end of the day you are still trying to sell a product. You might want to consider using some engaging graphics on your homepage, just to bring people in to your catalogue areas (which are nice and clean and easy to navigate - well done).
When you add a product to the cart, the "View Mini Cart" text overlaps your logo to varying degrees, depending on which browser you use. It is an issue in all browsers, though... if this is the logo you are going with, you might want to consider making it smaller so there is no interference with your cart scripts.
All the best,
