Brilliant, this helps a lot. Thank you.

I'm curious if you could show where your base attaches in the back? I've heard you say 'just below the occipital bone', but it would helpful to see where that is. Along those lines, how long does the hair come down in the nape area (hard to tell from a photo) ?

I see what you mean by the higher density in the nape area, the previous one you had looked better there. I think I will specify a higher % about an inch up from the perimeter.
