Great figure, lovely work.

Why not cut the tail off a DCUC G.A Cheetah?
Thank you. I really appreciate everyone's feedback very much!
The Cheetah tail is way off, both in scale, shape, and size.
Rod's suggestion is pretty much what I did for Starman: you take a piece of wire that is shaped to fit and then put clay over it. Not impossible, but the clay is not meant to bear any weight, which leaves it prone to cracking in instances such as this tail.
Just didn't want to chance it with a giveaway item, but likely I'll do it for my own copy!
