This is less about the likeness and more about how this will fit on the body, I personally don't like how you continue a little bit of the neck under the jawline, sadly you guys went with unnecked and it's too late to change that now
but if we have to settle for a neckless sculpt (which sadly is very inappropriate for david)at least try and do it the best way. I've seen some of your recent sculpts (walking dead shane springs to mind) and the way the bottom of sculpt does not follow the curve of the jaw and that there is actually a sliver of a neck under it just looks really weird, I hope I'm not the only one who has a problem with this...
Chin looks much better now! and thank you so much for the extra bottle of vamp blood! that is very nice of you!
O and the hair looks great too!
