Raid shot, in combat:

Party shot, out of combat:

(yes, non-pally tank in your pally thread

)
Done from scratch, fairly minimalist, I know there's some duplicate information like buffs but I like that.
I like that I've finally been able to integrate the Raid and Party frames in the middle of the screen without making it look like a total mess. I'm used to having all the information in the center, as it improves my tanking significantly.
Major addons:
oUF (with the excellent oUF_Nivaya layout), plus some plugins, notably aggro+debuff highlighter
Bartender4
DBM
Carbonite
kgPanels
MikScrollingBattleText
Satrina's Buff Frames (also takes care of my debuff timers above the rune bar)
Omen (auto-hides, when in combat it's next to the Carbonite minimap)
Recount (usually kept hidden)
SimpleRuneBar
The OS shot shows a nameplate addon which I have removed in the meantime and gone back to the cleaner Aloft.
