This one is just bloody terrifying full stop. Monsters hiding in closets or under the bed are a thing of nightmares for most kids. A skeletal type monster with crazy hair would definitely terrify me as child.
I am still debating on whether to have my characters face only with a peeling mouth and no other senses. I feel that without having senses, the character will appear much more scary, but I feel that using the senses and adding eyes to the character will somehow enhance the character as you can design them to look how you want them to.
Who has the right to say the pain of the living outweighs the pain already suffered by the dead? The only reason why people get away with saying this is because the dead don't have voices to defend themselves.
