Side project I was working on making my custom interfaces.
This will require KGpanels or similar WoW art addon.
There are 3 different styles; Dragon, Dark, and Heaven.
Dragon has only 2 pieces, Dark and Heaven have 4 (they include chat boxes or extra peripheral space).
Heaven UI has 3 different versions that can contain some pre-determined box placements, I also included the "blank" version in case the boxes don't appeal to you.
You can see how the Dark UI is setup on my Rogue by following this link
(i actually have the scripting and custom made unit frames for a "heaven" version of the Target/Targettarget/castbar etc, to work with ouf_diablo but that will take some extra work [not too bad but not something easy if you are computer illiterate] and I will be willing to give that out if requested)
Cleaned up the bottom left and right of the Dragon art as per ckramme's request.
