Post your 2.0 UI
Post your UI 2.0
To be constructive.
Hide your bag bar and menu bar. They're unnecessary. For bags/keys my favourite mod is called ENGBags. Find it on curse. Auto-organizes all your stuff.
Switch from Damagemeters to SWS(imo)
Your player frame and minimap frame could be moved up more to the top to free up a little center space.
Could also get Detached Minimap Buttons(on curse) so you don't have all those buttons cluttering up your minimap.
Could hide most of your ability bars, bind the abilities through bindpad, and then only show cooldowns with either a cooldown bar mod, or just showing a bar of 100% cooldown type abilities, in conjunction with OmniCC(on wowace)
You're not targetting anything, so I can't see how your target frame and ToT frame are set up, but I would assume they're in the standard "to the right of player frame" position. If that is indeed the case, I'd recommend moving your player frame and target frame to a more central position. Approximately where your feet are now in that picture.
I'd also recommend setting up a viewport of some sort at least along the bottom. A good mod for that is Skinner(wowace)
That's about all I can think of off the top of my head. For a general recommendation, I'd say go look through the thread I mentioned earlier. There's tons of unique and cool ideas you can see there. As it stands, your UI just looks disorganized, messy. A bit of touch up would go a long way. When you've finished making it "look pretty" so to speak, start working on more specialized informational mods.

Good Luck!
