A while ago I did an Estella Warren caricature that I thought came out really well. I hinted at her shape with color, rather than drawing with complete lines It was a nice effect, and I used it for this image of the Invisible Woman. I wanted to get the impression of invisibility while still, you know, actually drawing something you could see.
I also put her in the John Byrne reverse uniforms that I thought always looked pretty neat. The colors did well with the invisibility effect.
