Ambiance Browser Chrome

My first dribbble! This is a mini web browser chrome I'm working on for my new personal/portfolio website. It's going to sit on the front page with my latest project sitting inside, using google as a place holder for now.

I've designed it in the style of Ubuntu's ambiance theme, since I'm an Ubuntu user =]

I was thinking about adding a tab, feel that might reduce the cleanliness of it though?
