Pretty isn't it? I never much cared for screen shots as they leave nothing up to the imagination. With an "artistic rendition" from paintbrush you can imagine your own favorite add-ons and whatnot instead of wondering why I was targeting some guy named Napkins who was recently defeated in a duel by Coolguy (true story, kind of an inside joke now for stupid names).
Anyway I use a lot of the default UI and placement, since it is easier to transition as old mods die and new ones are born from release to release and sometimes playing on a computer without mods (gasp).
I also use the same UI for all my toons which is why I prefer mods that are more generic and customizable to something out of the box that only works for one class and/or spec. I've recently begun trying to standardize my action bars across toons as well so that similar abilities are in more or less the same places to have muscle memory work with me instead of against me when I switch to an alt. It was a little hairy for a while, but well worth it.
If you're at all interested in what mods I am using specifically I have a link to the right listing them all with links to go and download them.
