Maybe Catgirls can be Haibane too?
I drew this while sitting in a conference at the IBM IMPACT event in Las Vegas in 2008. I was worried about my flight the next day; the weather was horrible in Minneapolis and I feared a delay. I needed a little confidence booster, and this image (and the person who motivated it) helped me through.
The sketch is really messy since I only had one pen at the time. I tried to clean it up a bit -- remove the prep lines, fix some obvious errors -- but I could only fix so much without redoing the entire image.
