In her book, "Bobbi Brown Beauty", the renowned makeup artist lists the most common eye makeup mistakes to avoid:
Cat eyes: Black liquid liner that extends upward -- well beyond the outside corner of the eye -- is harsh and looks dated. Brown shadow liner drawn a tiny bit past the eye is softer.
Kaleidoscope eyes: Bright, shocking mismatched colors don't belong on the eyelid -- unless you're dressing as a clown for Halloween! Choose muted colors in the same family and blend them well.
Blush as shadow: Sweeping your blush color across your lids sounds like a useful time-saver (lots of makeup artists make this suggestion). I find that the rosy coloration of most blushes is wrong for the eye area and can cause eyes to appear red or pink. Instead, do the same one-color technique with shadow shades like toast or pale pink.
Unfinished liner: Lining only the outside half of the eye has a minimizing effect. You can choose to do only the top lid, but be sure to apply color all the way from the inside corner of the eye, continuing along the entire lash line to the outermost corner.
Shadow matching: It's almost never a good idea to match your eye shadow color to your eye color -- especially if you have blue or green eyes. Blue eyes look amazing with navy liner but disappear with blue shadow. In general, neutral colors that contrast with eye color work better.
Mascara clumps: It was the look in the 1960s, but it doesn't work today. The best way to achieve thick lashes is to do several thin coats of mascara. If you experience clumping, wipe the excess mascara from your brush with a tissue.
