Thanks, Ptrope!

It's not perfect; the jaw looks like it's being "peeled" if opened past a certain point (so it's a challenge to stage an "atomic breath" pose), but I achieved what I had hoped, filling out the lower jaw and the brow region.

I like the body Scott_A modeled, but I've often "frankensteined" the head of his "Delgadosuarus" to get the more "saurian" look I like (as in the render above).  But it's a crude approach, the head and upper neck simply positioned with the neck and body of the GFW figure, the geometry overlapping.  The displaced material acts like a kind of virtual "spackle", patching the ugly seams.

Sincerely,

Bill
