Again, giving myself the heebies here with a tale about one of my own personal nightmares. Getting the reference photos was a bit of a nightmare too as it was done by myself, so you can imagine the contortions required, not to mention holding a camera and a torch at the same time... 
 
The drawing comes complete with a copy of the story by Sean Walter.
 
Worked in charcoal and Wolff's carbon pencils on Fabriano Artistico extra white paper. It's framed ready to ship in a smart black frame made using recycled materials and with acrylic safety glazing. Drawn area size 12" wide by 18" high, frame size 16" x 22".
