I read Brandon Sanderson's Mistborn books in March and loved then. Kelsier is a very memorable character that really drove the books. Even when he wasn't in the thick of things, he still influenced all the other characters around him.
This scene comes from a point early in the first book when he is battling Hazekillers, folks trained to do battle with Mistborn warriors, which is what he was.
If I really wanted to do something amazing, I'd love to try my hand at depicting his fight with a steel inquisitor from late in the book, but that isn't suitable for a sketch.
