What a demon indeed! with only a few traces of finger smudged / scanned pencil work, this baby puts fear in my eyes, and makes them burn because of the photorealistic fire.
There are three things that make this picture scary.
1. Red eyes
3. Penguins / penguin esc robot guys
The fortshortening on the snake head is perfect, and symetrical as it should be.
The penguin thing is also missing its red eyes, which makes the fourth scary item in this image
4. Absence of eyes
