I have trouble drawing convincing blood/tears/sweat/et cetera. Do any of you have some advice that could help me? (Laugh at my horribly short post. Ha! Ha! I'm so blunt o_o)

I can only give advice on blood. (Whoo, does that say things for me. o.o) Anyway. The most advice I can give you, is make it a dark red, not bright, with possibly purple/brown shadows, and make sure you use a thicker brush. Because...blood is thick. Yes. ~_~

Make it dripppppppp... =]
