The Ghoul!
Nothing fancy , I used latex to build up areas around her face and neck, then painted in the areas I felt needed some attention.  Her hair was sprayed with black hair paint to darken her color. 

This was rushed and had to be completed in about 15 minutes.  Not bad for a first try!
Here she is!

Like I said, 15 minute window of opportunity.
