Thanks for the complement, I was thinking of cuttin' the teeth and upper lip and forcin' them just a little bit forward. It worked really well with the lil' bat from Paperbox World: http://www.fileden.com/files/2008/3/9/1804477/BAT.pdf
(Come to think of it, I haven't even posted that one. Shame on me.)
Just found out you are an LA guy. Will you be a the Scion show on Saturday night? I teach graphic design and I have built a few of your models. Very complex and challenging round heads. You are a master. Hope to see you there.
