The head's not big, it fits the refs perfectly. And that is a shadow behind his antenna that makes it look like the head is going inward in the front pic. If you look at the side pic, you don't see the shadow and everything looks fine.
I did make a cape and turban version already(I'll post pics today or soon after) and I plan on animating it. I've already done a few animations. But I had to get rid of the right and left foot bones and the right and left hand bones so I could add more bones to the original Piccolo skeleton. Because everytime I tried to add bones(for the cape) with the feet and hand bones still present, they (feet,hand bones) would twist in weird directions. Does anyone know a way where I can add new bones to the default Piccolo skeleton and still have the feet and hand bones not twist around?
