Wonka's Marker Art

I draw pictures with pencil, on white stretched canvas on a wooden frame.
Then I color the picture with black and grey markers. I occasionally add red, blue and green to certain pictures for a pop of color.
Subjects that I have are: Marilyn Monroe, Audrey Hepburn, John Wayne, Tombstone, Harrison Ford, Elvis, Superman, Batman, Frankenstein, Jason, Blues Brothers, Beatles, Tom Petty, and many more.
