NightBlade: Injured

Just practicing drawing my OC. I need to get very good at drawing him, as I plan on creating a comic based on him. I tried seeing what I could do with nothing but grey-scale, and I think it turned out pretty good.

Sidenote: If NightBlade looses a limb like in the image above, it will grow back within about a week. The chains protruding from his arm begin to wrap together and form a new arm slowly over time. However, that doesn't meant it wont hurt like hell
