Thanks for the feedback--if I come to Centerfold this year I'll teach the Dragon.
All I really changed on the dragon is the shaping of the head and wings, not really anything else.
And yes, the 4LCWACWACOIBOIB is from a single sheet. It's just a bird base, but I'm not gonna go too much into the details. It's pretty much just sinking and unsinking for about an hour straight, though, so not very fun to fold.
