This is a design I did for a Polka Theatre production of The Starlight Cloak.
The story was based on an Irish version of Cinderella called Fair, Brown and Trembling.
It's always nice to do a one-off image like a theatre poster or a book cover. You don't have to worry about repainting the same character in different poses, and you can concentrate all your creativity in one picture rather than pacing yourself over the length of a book.
This one was from 1995, when I was looking a lot at the work of Gennady Spirin, and I can clearly see that I was trying to emulate Gennady's clever way with shadows.
