Overall the site looks really clean. Only a couple minor things.
Images should be optimized. If you have access to an image editor (Photoshop, Illustrator, Fireworks, etc), use it to export the image to reduce the file size. If not you can use an online tool like Yahoo’s [Smush.it](http://www.smushit.com/ysmush.it/ “Yahoo Smushit”). Sometimes Smush.it is down though. They could be reduced by half in size.
I might also suggest aligning the nav Left, instead of right. When the nav is that wide, aligning it to the right doesn’t come off as visually appealing as it might if it was just a couple links.
When the mobile nav is up and you open the drop down, the Home, if high lighted, touches the button, should be a small gap.
The footer has an empty list item with an unused class. First link also has an active class.
When dragging the Contact form Text field, its changing the width of all the form elements. Not sure if thats intended. Might want to put a max-width:100% so it doesn’t get out of hand.
Couple other small things like html that can be reduced in some places, usage of classes/ids.
I’m really impressed. It’s a good looking website.
