Love the design!!! 1.- Triangle idea reads clearly. The only thing I'd change its maybe avoid the soft curves you have in the left hand, make it so the fingers look more solid and sharper. Also the armor on the same hand exaggerate some of those triangle shapes, specially because its the hand closer to us. 4. Crystals: My first thought was to add them on the back. Or maybe the top of the head can be a crystal that powers him up, you can use that as an excuse to make his eyes glow. I also noticed that the hand coming towards us and the torso are the same size. Maybe push the foreshortening a little more to make the hand a bit bigger? Also the rocks on the "tail" most of them are the same size, more variation may help with depth and interest :) I hope some of this helps. Again the design its awesome! | Artwod Feedback
