Agreed. As to changes for a better sell, ill add my 2 cents. Lighten the skin tone down a bit(not too grey but not still looking like living flesh). Like Shins said, take some of the neck chunks off or thin them down, they look just a bit too pudgey as for the fingers, I say leave them. One of the major things buyers(both collecters and kids) like is poseability. Hacking a few fingers reduces his ability to hold things besides his head(suppose someone wants to add their own items, etc)
Looking good though, hope he sells for ya

HMM, I can't think of a joke about that yet, but it won't be long.
Anywho super custom keep up the good work.
Thats it!!
This neither the time or the place to lose your head.
He`ll never get ahead I'm life.
