Here's what I look for on the head. Looking down from above, I like to see width. A wider skull just suggests intelligence and dignity to me. Second, I don't like to see a flat top haircut look, like the old guys used have their barber cut their hair back in the day. I want to see the curve be smooth and continuous, making a pleasing and full arch. I've only got Rock photos that sort of demonstrate what I'm saying, so I'll not pollute the space here. But folks with NHs might be able to use the photos up to point out a good, regal head. I hate a crow's head look on any bird. Again, I've only read the SOP to death on the Rocks, so I've got that burned into my brain and my fixed memories and mental images from long, long ago.
