I saw this image and am working on a project that needs a 4 part measuring meter for an RPG, and really like your layout. I hope you don't mind, i'm not stealing it, i just like the idea you have with the orb and the bars coming off from it. In the edit from the mockup it looks like you extended that middle bar which helps make it more prominent. perhaps seeing it full, half full, and empty will help, with critiques, I'm assuming that it wont always stay full.
