Piper and Jack designs

Sketch of two characters from a story I'm writing. Piper is an asthmatic flute player with an emo-punk sense of style, and Jack is a green man. I've enjoyed writing about them and I had a strong image of them in my head, so I thought I'd put the design down on paper. One of the first sketches I've uploaded in a long time...

I'm drawing an actual illustration with the two of them, as opposed to just this character study, but it's not done yet so I don't think I'll post it yet.
