not great
You're teaching people the wrong stuff, you never want to shade with the brush tool, because it becomes bulky and noticable, instead of looking engraved into the object. (your shades dont look as realistic as they could be.)
blood shouldnt just be a bunch of dots!!!
there are 2 ways of making stick figures, lines, and brush.
please make sure YOU know what you're doing before you start giving flash lessons about it.
and everything isnt to be drawn with brush.
