A creature without hind legs, a long, pointed tail, sharp teeth

a creature without hind legs, a long, pointed tail, sharp teeth, I have a bone mask that is smiling in a macabre way, My eyes are red with white pupils, some big wings that are my front legs, My body is completely made of flesh without skin, small sharp bones sticking out of my back, I have a not very strong but somewhat disgusting smell and sharp bone claws
