All personal opinions!
Get Align so that you can make sure everythign is centered or on the same levels.
I would remove the HP defecit numbers on your raid frames. As a warrior you really don't need to see that player X is missing 56.8k hp and it would make that part cleaner.
By the look sof it you keybind as such I would highly recoment removing the gap in your abilities to tigten that up and even hide as much of them as possible ot free up more realestate!
It looks like you are using Raven and I can only assume that the Large greyed out cd's dragon roar, CS, HL etc are there to let you know when you can use them. If you are using raven may I sugest the following instead. Set up a custom bar and set your DPS priority and have only 2-3 icons show up. Have them set in order of when you should use them and have the CD hidden so when they are not available they wont be visible. This will remove allot of clutter as you can focus on what is available and shoul dbe cast > looking all over at whats on cd what comming up etc. You may also want to filter the target debuffs to only the ones you need to keep up, not really sure if you use any of that information (I know personally I don't care that my target has rogue poisons on it or lock dots etc).
I would hide / remove all the incomming healing.. as a war I don't care about the healing #'s I get or what spell it is I just care I'm alive if I die ill look at wol after raid and see wtf happened but I know for sure I wont be able to pay attention to the fight and keep track of all the incommign heals I'm getting! Also I would move your dmg text as it it clipping into your boss timer bar and your target debuffs.
You have grand empress bar and HP and 75% shown 3 times on your screen. I'm going ot guess it is target, boss frame and focus? If it is not and it is 2 boss frames then get rid of one as having the same info in tripple is not needed.
I would aslo ditch Omen looking at your target nameplates you can see that "glitch" has agro and you are far form taking it. This is a much better location than off to the side (where Omen is) to see where you are on threat. however being melee I get you cant alwasy see the name plate so perhaps making omn smaller and placing it under your unit frame would be better? I just can't see it being usefull off to the side away from your focal point.
like I said just personal opinions take it with a grain of salt
