@ QuiGonFishing, for the futzing, the main thing I do is pull the glued down hair off his chin and define the 'stache a little more. I also pull the hair up a little around the eyes and sides of the head and then comb it back down.
I just got Chewie and agree the best change you can make is to get that hair down from under the jaw. Without that change the chin pokes out too far and just makes him look wrong. Am so glad I've got him (also at a discount). I was put off for ages by the proto pics and first in hand shots. But with this change and few others he's standing next to Han looking awesome !
Anyone still on the fence should get in now while you still can.
