Phantom Girl from last year. Like PG, I did the Cockrum designed outfit from the 70's that I grew up on,with the nod to her current design with the arrows in the boots, which I thought worked surprisingly well in creating a retro feel. Watercolor and ink, with some photoshop touch-up.
I've always thought that Light Lass wouldn't be all that effective in a fight, what with her powers to make things light as a daisy and all. But she sure is cute!
