When I first began coding wordpress sites I would do what most new designers do.  I would look at an existing design and then add and subtract from it until it was close to what I wanted.  The problem with that was that the code often became messy, had extra lines, and would break in obscure ways down the road.  Updates became nearly impossible.  The first site design that I ever created without this method, did really well.  Artists loved it for displaying their work.  It was essentially nothing but a header image, a menu and content below.  However, that was two years ago, and since then that code is now slightly depreciated.  I have opted to upgrade the entire design as a child theme to twentyten (the new default wordpress theme).  This theme fully supports all of the twentyten features.
