Love it, you're making it look even better with each WIP. Only criticism I have is I think you should make the energy in the back run down into that groove that continues along down near the eyes; see what I'm saying? the energy storage kinda just ends into a straight line in the back, would look better if it continued into that groove
Hm I feel like you ran what could be a amazing head into the ground, the last WIP is too much for me, but idk

hm, Ive changed my mind
welp, I love it
Keep making new heads
