Famous Fictional Villains: Riders of the Apocalypse!

Tomorrow night, Friday Nov. 6th, is the opening for an art show I put together here in St. Louis at the Mad Art Gallery. It's another one of these "Famous Fictional" shows in which local artists draw portraits of characters from popular fiction, in this case, books and movies.
These are some rough sketches for the posters I printed up advertising the show.
The rules for the show were:
1) Each artist makes two pieces the same size and shape
2) One piece from features a character from pre-20th century literature. This includes everything from ancient mythology and religious texts through 1899.
3) The second piece must features a character from film.
4) Both characters must - to a reasonable degree - be recognizable to casual viewers
5) Both characters must be VILLAINS! The characters I personally chose are The Four Horsemen of the Apocalypse (from Chapter 6 of Revelations in the New Testament of the Bible) and The Lone Biker of the Apocalypse (from the 1987 film Raising Arizona). Some sketches: My paintings are big sheets of Masonite covered in fluorescent orange spray paint, silver leaf pen, acrylic paint & india ink. Here's an early in progress shot of the Horsemen:
And here's a detail from further along:
And here's a sneak peek at the Lone Biker:
You should really see the whole paintings in person to get see how bright this construction orange spray paint is. It should be a fun time. It goes from 7 - 11, radical DJ Tone Wolf will be playing songs, etc. See y'all there!
