I have a drawing that I want to add realistic looking blood flowing from a wound on the characters face. This drawing is done all on paper and can not have any computer/photoshop aid. Any ideas / techniques on drawing realistic blood? I have thoght about using Red Fingernail polish and even my own blood but I dont think it would look right once it dried. I have also thoght about using watercolor pencils which I have just started playing with. Thanks for any ideas / help.
