Painting My Insides Out

As was my intention,
This painting is something hideous.
Blood drips from it's teeth,
It's stare is quite insidious.
The heart burns anxiously,
It is simply igneous.
Filled with morbid thoughts,
It is obviously pitiless.

Eating other hearts to fuel it's own.
Deforming it's own bones.
Likely accident prone.
A heap of bodies is it's throne.
Releasing a painful groan.

Some think it's a monster.
Some call it an elf.
Others think of a demon.
I call it myself.
