I’ve used snake skins plenty of times. The wet skins will lay down fine on the muscles. Just make sure you squeeze the access glue and air out. I’ve used prairie rattler, western diamond back, Texas broadband water snake and garner on HHB.
My favorite are Texas broadband ( search This is not big Al) and I really like garner( search A walk on the beach) Hopefully you can find them adding Bjrogg might help.
I’ve also used a airbrush, stencils and wood stain with some pretty cool results. Try searching (Deep Roots) and ( Sugar Shack).
Also (Leap Year) is a combination of skins and airbrush
Hope you can find some inspiration. Or at least the threads.
