Raven in the Ketta's Vision of the Future

Raven was given a potential vision of her future where she was evil and ruled the world with an iron hand. When I read it, I imagined a fiery scene with Raven sitting on a demon throne. I like this picture but there are a few things that I'm concerned about.

1) I'm color-blind. Red-Green deficient specifically, so I can't be sure that I didn't totally bork the colors.
2) She doesn't seem that evil in the picture, she just seems rather smug.
