Thanks man, and nice images of Billy's face, I actually can see some Sonny in the sculpt in your images, a good repaint could probably make him look just right. Am I right in assuming there's no skin texture, just a very basic portrait, looks that way. I should have Dutch and the Predator in a couple weeks.
As for the neck mods. It seems like calvarenga's and tyler's are pretty much the same end result give or take, just different paths.
Calvarenga's is to shorten how high the ball joint is so the head goes further down on the neck, Tyler's is to deepen how far the exsiting ball joint goes into the head.
Too bad Calvarenga's requires an uncommon neck adapter to achieve because I like the result.
