Very nicely done - beautiful in fact. Seems like a bit of overkill for raiding, but for PvP I think it would be pretty sweet. I recognize most of them, but would you care to post what add-ons you used to configure your UI? I'm sure people would appreciate it - I know I would. 
I'm happy to provide that for you
The Screen shot you see above contains the following:

Error Filter
IceHUD
kgPanels
KHunterTimers
Mapster
NugComboBar
OmniCC
PowerAuras
Prat 3.0
Recount
SCT/SCTD

Yorsahj Automatic Raid Warnings
Sell Junk
ReforgeLite
RaidslackCheck
OneBag3
OneBank3
Overachiever

Ackis Recipe List

Some of the Power auras just like some of the addons are not used in both PVP and PVE. Some of the auras pictured above are only active in my PVE or PVP spec. Just like MOGit, reforgelite and Ackis Recipe list, which are also used when needed and left off when not being used.
Thanks a bunch for the post, I am very glad you like it. My UI is a constant work in progress for me so I am always looking for feedback! If you want my WTF file as the setup for this is ... a bit tedious lol I'll be happy to provide that as well
Cheers,
Kilgan.
