This is my UI called EpicUI (because I took the same item color code from WoW), it is a work in progress since Nostalrius but I'm now able to play with it smoothly. I only need to work a bit more on the back-office (lua/xml).
A few words...
EpicUI is a step away from TukUI, PfUI, ElvUI and others, I wanted to make something different and build my own identity. The guidelines have been to keep it clean, refined and instinctive to use.
Basically it is quite classic except for a few things like the unusual minimap put on the left and the two icons (over my Minimap and DPS Mate windows). Those two icons are acting like a signature as well as a button, the one over my minimap is displaying all my minimap addons icons and the one over DPS Mate is displaying its config window.
