>>5787113anon, i want you to think about the nature of a demon
i don't know for what reason you're trying to draw one. maybe you're bored, maybe you're doing this for a story. either way, truly think about the purpose of the demon.
is your demon is fallen angel, a monster, an evil spirit or a deceased villain? why is its soul tortured? why does it hate the living and how does it bring misery? how does its form reflect its divine punishment? How can it reach our realm? what does it do in hell? what does it fear?
