what Seiseki said, and drawing a diagrammatic pointing out what is what isn't going to help if it was for example in a game, rework and simplify you're forms, you are trying to tackle something I'm inclined to suspect might be a tad out of your range, colours aren't too bad, and some of it does reads like rocks, I read it along the same lines as Seiseki did torso, head and arms.
suggestions on increasing readability, try using a separate colour to define some glowing eyes, give him a protruding chin and strong mouth line/underbite
