it’s nothing new but it’s a nice one. i would add a contact form, and you should show paragraphs and headings in your preview. the definitions for lists should be revisited. it’s all pretty much standard settings in your theme.
the idea with the "jumping" navigation was a bit irretating to me on first sight.. hmm. what else. you should make the gallery to stop on hover. and i just saw that your h1 headlines are not in the optical middle of the bars. give them more space under the words than above.
