If the certain member is the one I'm most certain it is, I've worked side by side with him (and am proud to call him a friend), on more than one shared project project. And I can assure you it is

Use other's work as an inspiration and a motivator. I did with the

mine better because its
mine!
Sculpting is the "Final Fronteir" for me - one of the last (if not the last) skill I have NO experience in. While it's easy to offer constructive criticsm, and play armchair quarterback, there is no
