I am a huge fan of H.P. Lovecraft, and this drawing was inspired by his poem The Nightmare Lake. Originally, a passage from the poem was going to be written inside this creature's body, but a lot of ink got spilled on the picture (from those damn Rapidograph pens) and the body area had to be painted in to save the drawing. The passage read:
'I saw the stretching marshy shore,
And the foul things those marshes bore;
Lizards and snakes convulsed and dying;
Ravens and vampires putrefying;
All these, and hovering o'er the dead,
Necrophagi that on them fed.'
Coincidentally, H.P. Lovecraft and I were both born on the same date: August 20. Apparently, I mention that a lot. I hadn't noticed.
