I really like the page navagation, nice and easy to move around. To second someone else's suggestion, I think your feature pen needs to be the focal point of the page. More pictures and less print.
To be honest, I really do not like the logo. I know my eyes aren't the best, but it took me a while to figure out the "Diverse" word. All and all, as a comsumer who buys a lot off the web, I think the site has a ton of potential.
One thing I have been wondering about though. Is it possible that there are just too many choices? I would assume that most people buying a pen would not know what any of the styles look like and each style would have to be checked out. Is that a plus? Or a minus? Not sure.
The last observation I would think that Handcrafted Writing Instruments" a more prominant place on your home page.
Good luck and I think you are on your way to an awesome website.
