Hey there!
A few months ago I started to work on an UI, which used the BlizzArt (or Blizz-like) textures, as I really love the artwork from the standard interface, but used a different layout. I never played WildStar, but I really adore the interface, I think its the best standard ui out there. So, I sat down and tried out different setups, which were good, but not perfect. Now I am almost done, still need to do the WeakAuras for the secondary resources (DK, Pala, Affliction-WL, Arcane Mage are done.).

Here are some screens, hope this ui isn't too bad!
Also i wanted to thank Daedhir, who made DaedhirUI, as he gave me alot of inspiration (through his now deprecated UI) and i used/modified some of his artwork
