well, that's very bad, I admit, but I started colorizing on a bad photograph of an the unfinished sketch. on top of that, I never CG color anything because I simply suck at this task. however, I wanted to see the blood red on this sketch, so... I adjusted the brightness/contrast level. I decided that I was too lazy to (re-)create the sketch using paths, so I opted to just use airbrushes over the sketch. therefore, I quickly laid out the base color for the skin.
