Portraits are aways a cool excercise! Used as classic shading practice. I´ve began with the highlights - using the paper whiteness itself while I smudged the midtones areas, then the shades and back to the hightlighting final touches using the kneaded in some spots. I blotted the make up and put some vampiric eyes on her just to make a good contrast ! ;)
