Anybody have any ideas based on the attached sketch for a font I could use to start out a logo project? Many thanks.

How about http://ITC Vinyl?

Maybe Stiltskin?
Try Birch, too.
The first thing that came to mind was Abaddon or Drakon
Another idea might be Girlfriend. Try searching 'halloween' at www.myfonts.com.
Your sketch is pretty nice... have you considered scanning that and drawing the logo by hand in Illustrator?
Just ran across Talon from Font Bureau and remembered this post.
I keep finding more of these while trying to ID other requests.
CCTreacherous-Curves from Comicraft.
That Comicraft font seems to share some features with Abbadon, which was a Dave Nalle adaptation of a typeface by Alex Jay for a 1981 book called "The Dinosaurs" by William Stout. Jay's type design was inspired by lettering of Alfonse Mucha, the Art Nouveau illustrator and graphic artist.
