Thanks for the compliments guys -- as Martyn says, it's a lot of work, redos, rethinking, etc., but it's very satisfying in the long run. And expensive. But satisfying. ;-).
Also as Martyn says, there's a lot of reconciling between two differently detailed miniatures, decisions as to whether a particular feature is a design element or a mistake/shortcut, and extrapolating into areas where reference material doesn't go. All the typical dilemmas of trying to make a model of, well, a model. I've relied a lot on Martyn's trailblazing -- he's really figured most of the hard stuff.
Neo- uk -- the parts are surprisingly sturdy, but there is an armature made of laser-cut acrylic sheet inside holding it together.
And again, I really appreciate all your kind words!
