Great brush choices on this. Personally I can't stand the texturing of brush strokes across wide weaved canvas (or canvas in general); just personal preference. But the textures work so nicely on this, it is hard to dismiss it's effectiveness. Really grainy and aggressive, sutis the character perfectly. Great continuity with the light source, and the variants of dark color at the bottom is terrific... love the build up and movement there. Maybe one of your best, but I am a big Batman fan. This is a superior illustration of my fave superhero.
great drawing!
