Well, first off, that writing is really smooth. How did you do that? Is it actually freehanded or is it a really nice font? If it's freehand, I'm jealous.
The lineart on the figure itself is also incredibly smooth. And as always you have an impeccable eye for detail. The texturing is very well done, the water stain and the ink splatters are particularly nice touches. All in all... you know, I really can't think of any way to improve upon this image, rendering this critique somewhat useless, when you think about it. Ah. Yeah. I'm looking really hard, and I can't find one single error. Good freaking job, dude.
