This is a fun variation.
When I was doing the flames on the Black Queen litho, I had the background on one Layer, Jean on a second, and I was doing the flame highlights on a third.
For no good reason, I turned the Jean Grey Layer invisible, and was interested to see that the highlights still described her shape. I filled in the Jean Grey Layer with black, and it made for a really neat-looking silhouette.
Sideshow liked it, and used it as a teaser image. I'm including it as a neat little oddity.
