The Music of Erich Zann

Here is a color rough for my weekend project. I finally have some time off in my schedule, just enough, I think, to finish this piece. Its an illustration inspired by H.P. Lovecraft's "The Music of Erich Zann". The story's title character is an old, weathered man that lives in a strange apartment whose window happens to be a gateway into a dark dimension of unnamed terrors; he keeps these shadows from the stars at bay with his bizarre, haunting, and horrific violin melodies.
I hope to actually finish this over the long weekend so that I have at least one painting I could potentially submit to Spectrum this year. The other potential piece is a secret...I'll post progress once any is made.
Also included in this post in the charcoal under drawing. Enjoy it while it lasts, 'cause it'll be covered in gesso by tomorrow. That's right its a free-wheelin' painterly painting. An attempt to repeat, if not improve on my results from my "Frank" painting.
