This is my HUD. There are many like it, but this one is mine. I've gotten a few questions from various people about how to make the rings show up around your character, and this is how I do it. ArcHUD, like other HUD mods, puts meters for your health, your mana/rage/energy, your target's health, and other things right by your character where the action is, so you don't always have to go looking up into the corner of the screen. In the screenshot, for instance, from left to right, the bars are: my mana, my HP, my casting bar, and target's HP. Near the bars, you can see text for various things: the name of the spell I'm casting (lol, Smite), my HP and MP in numerical form, the time left on my cast, and my target's percentage health remaining. Below all that is some extra info on my target, target of target, and target of target's target, along with a nice little 3D model of my target (this helps to quickly see who you're targeting when healing).
