It's a clean design
The only thing i'd look into if I were you, is the overselling tagline.
More often than not, those who draw attention to "we do not oversell" on their main page, are vicious oversellers in truth.
This is not to say that you are overselling. This is simply the impression I get when I enter your website.
It's all about the breadcrumb trail.. you're immediately putting an alert out there by leading with a negative. You should always lead with a positive.
Just my thoughts
