There are some redundancies, like using text to read "Black and White" on what is obviously a B&W photo. Or having a "contact" link next to the email link. I would also move "portfolio" before "bio" because that's what the site should focus on it it's intended to be commercial. The pictures first. Bio, to a buyer, is often a who-cares issue.
Who is your intended audience? Publishing buyers, or individual print buyers (or other photographers, who oddly enough are a lot of buyers)? The answer will have an effect, surely, on which pictures you show first, to draw them in. Magazine buyers rarely give a hoot about landscape, go with the people.
