Unlucky Break

The inspiration for this came about a year ago (it's already been a year???) when my dad broke his leg. I really really wanted to draw automail on the cast, but he wouldn't let me...
Drawing this was the next-best thing. I nearly finished it, and then I left for America. I took my laptop, which does have Photoshop on it, but I didn't take a copy of this. Now I'm home, and I remembered it, so I finished it up, and here it is!
