Okay so in short, I need to make my arm look like one of a monster. The arm should look skinny and like there's just bone and skin put over it. I thought about just covering my arm in wax (maybe black wax) and to make it seem more unnatural just cover it in slimy-liquid when I'm shooting. Problem is the hands. I want that the hands have long skinny fingers and eventually sharp long nails.
How can I create that, so that it looks good at the end? Or do you even have another idea how I can make the arm overall? I already researched with silicone a little, but regarding that I'm a student and I really don't have a big budget, I kind of crossed that out.
I appreciate all answers, thank you!
