At first I wasn't sure what was unique about this Fett, but then I saw those legs! Awesome job. The full articulated hips look great on that figure.. Which ones did you use?

Very nice!

I'm curious of the recipe, myself

actually I did more than just a lower torso swap but to answer your question, the star wars figures are so small i had to use a scarlett lower.
to fit smoothly after adapting it i then made sure it would all smoothly fit together,without losing out on any articulation, I then did alot of sculpting work for the legs to make them look as accurate and natural as possible, then I braided the wookie pelts and repainted most of the figure there were some other little things I had to do but I have been working on this gut for a while.
