I've seen Serenity twice actually [not 4x], and just bought the Firefly DVDs -- I love it all. There is life after Stargate! New Diavo hair based on my own when it gets long. It took numerous sketch attempts but I've managed to capture the look I want. I really like the color theme going on in the first two panels.
