I know an artist named Alison Nichols who agreed to take a shot at illustrating some characters from the book. She also reached out to one of her friends to do the same. The top picture of Flarence is her work. The lower image of Soleil was done by Lothar Speer. I think they both did a great job. That smug grin is exactly what I imagined when writing Flarence's scenes and I really like how Soleil's poisons look like they're being directed through small cyclones.
