This is my last-minute entry for the PMC Lovecraft contest. I literally spent about half an hour, total, on this beast.
This is Charles Le Sorcier from H.P. Lovecraft's story "The Alchemist". Spoiler alert: he's the alchemist.

From the story:
"When at last I turned and faced the seat of the sound, my eyes must have started from their orbits at the sight that they beheld. There in the ancient Gothic doorway stood a human figure. It was that of a man clad in a skull-cap and long mediaeval tunic of dark colour. His long hair and flowing beard were of a terrible and intense black hue, and of incredible profusion. His forehead, high beyond the usual dimensions; his cheeks, deep-sunken and heavily lined with wrinkles; and his hands, long, claw-like, and gnarled, were of such a deathly, marble-like whiteness as I have never elsewhere seen in man. His figure, lean to the proportions of a skeleton, was strangely bent and almost lost within the voluminous folds of his peculiar garment. But strangest of all were his eyes; twin caves of abysmal blackness, profound in expression of understanding, yet inhuman in degree of wickedness. These were now fixed upon me, piercing my soul with their hatred, and rooting me to the spot whereon I stood."

So, uh, that's pretty much it.
As always, feedback and constructive criticism are appreciated.
