Here's one I forgot about but it's one of my favs. When I asked Chris Giarrusso to do this pic I paid him for it. I then decided I wanted another drawing done by him and once he was done I was so excited that I walked away without paying for the second one. As soon as I realized it I ran back and gave him the money. I asked him why he didn't stop me and he was like, I dunno. True story I swear.
This one is fresh and just in from Manuel Preitano. Here's his note on it: Sketch I did eperimenting with http://www.brushesapp.com/
I love the look to it and the whole noir feel to it.
