Inktober day 7 Alchemy

Still a day behind, but whatever... ^^ I actually had a lot of fun with this - I drew it this morning just before our group meeting at work, so I had to be very fast. The character is from one of my stories, she's called Mirainn (pronounced Mee-run) and she's actually an alchemist, so it was kind of obvious I'd draw her for this prompt.
I noticed something interesting: when I mix the white and the black ink, I get a cold (!) grey - I didn't expect that because it's a warm white and a warm black, but obviously, particle shapes and their interactions with light ware a complex topic. Anyway, I tried to use this to portray cold, almost blue-ish light on a warm background...
