Well laid out site using almost everything HTML5. Good use of tags to form structure (though using article and section indiscriminately for much the same purpose). Footer element completely overloaded incorrectly. Could be much better accommodated with an aside (or even another section) with numerous nav blocks. Good use of new input types in contact form. Also, seems to be an effort to maintain header hierarchy across different sections (though in design all rendered very differently). If this is the design intent then this is fine, but otherwise incorrect in HTML5 treatment.
