Aye, Longtime Lurker Here! My First Custom is a 1:12 scale Movie Deadpool figure. It's composed of primarily the overused ML Eel/Blizzard figure base body/head, and WS Cap's Belt. It still retains all previous articulation, thanks to my endless sanding prep for the figure. I know it's still pretty rough, but this was my first time sculpting or creating a custom action figure so don't be *too* harsh with your judgement :D
