This is mine, I recently tweaked it. It has usability over looks, but its pretty tidy I think
The addons I use and their rough locations:
Unitframes: Shadowed Unitframes (Party, Char, Target, Target of target, target of target's target)
Top bar: Titanbar
Actionbars: Dominos (ontop chats)
Minimap: Sexymap (down, center)
Recount (down, left)
Omen (down, right, not really showing)
Cooldowns: Coolline (ontop minimap)
Runes: Magicrunes (ontop Coolline)
Procs, important abilities: Power Auras (ontop Magicrunes, not all procs showing)
Raid: VuhDo (center right)
