Feels like it needs ... more? less?

[Landrell]

So, I've been floating with this UI for some time now. The first shot is what I'm currently with now, it's clean, clear, and as crisp as I can get it. The other shot is in party mode, so ignore the rest of the layout.

Some of the addons I'm using...
-oUF_Nivea
-Chatter
-Wanderlust
-Tinydps
-Bartender
-Shinybuffs
-Tiptop...

So, I guess what I'm looking for is just general feedback, seeing if there is anything from another person's perspective that may see wrong, or what can be adjusted, etc. Just something feels off on it and I've been having a hard time placing it. The only thing I can think of is maybe the usage of real estate?

Not sure, but C&C always welcome!
