Catboy or Batboy?

Um, you may have figured out by now that I very rarely draw yaoi/shounen ai stuff, I feel more confident drawing the female form, and leap at the opportunity to draw ecchi fanservice of that .... (though I try not to show too much of that, I teach drawing workshops for all ages, after all!)

So this is quite rare from me. A gift for a friend whom I had been promising this for about a year -_-;; just ink/lineart really, a bit of touching up in Photoshop. Drawn at the Bristol Comic Con last week.
