Definitely a LOT of very well done directional punching work around the face, hairline and detail areas. Hat's off to Howard there.
According to Howard's thread on the first transformation head, it was a mix of NFT and punched.
From the pics, it looks like some of the dense areas might be NFT's fabric backed hair and it looks like the shoulders could be a lace-backed hair... it's not unusual to use a combination of fabric-backed and punched. (and to achieve a look like these, it's pretty much ideal).
Not trying to take anything away from it, of course! Like I said, that's the ideal, professional way to achieve the look of these guys and the result is INCREDIBLE!
