Use a tripod: Since you'll be shooting with a small aperture, you'll need a longer shutter speed. Keep the shot crisply focused with a tripod (and if you can, a cable release).
Remember the Elements of Art:** Specifically, line. Back in high school art classes you learned the elements of art and principles of design. By keeping lines in mind (where are they taking the eye?) you will get a more interesting shot with depth, scale, and focus.
