This is my concept art about the man with four arms.
When i create this concep i think: The torso of the man with four arms is very heavy. How a man with four arms can be raised?
This days I see the King-Kong and think: The half part of the man with four arms could be an Ape... Then when the man walk he walk like an ape, consequently the body could be hold by the large and hard torso.
I think about the bones structure and the muscle structure. A give to him monkey muscles, human muscles and Horse muscles (I used neck horse muscles in the union of the monkey part and the human part)
This is my first concept to a real movie monster.
