Awesome! Progression! Love the clarity, one remark would be that the glow or dust/blow FX on blackie's right arm was a little hard to read, I kind of miss hints of transparency there, maybe some parts of the lineart could've stayed in there (but this is just the devil speaking, the "it's never finished" syndrome, pay him no mind)
yeah I know what you mean, when working in flat colours its hard to make some lighting effects more realistic, so its either a choice of sticking to the style your working in, or trying to make something unrealistic more realistic. I can never decide!
