what I do is just wear mascara. I've asked all my guy friends if they prefer mascara or eye liner. they hate eye liner, say its not natural looking. where as mascara just makes your eye lashes darker, hence more visible. as long as you only put one to two coats on. and when I feel like going out, I put eye shadow on around my eyes.
You have long, lashes with volume like I do. :) Just wear one coat on your top lashes of elongating mascara only, it will add just a nice pop to them.:) And you have thick bottom lashes so..with mascara they may end up unnatural looking and clump.
Yes, a light brushing would really enhance the look...and I used to think my look was too heavy with eyeliner and mascara then I realized that was only because I wore too much eyeliner now I wear less eyeliner and mascara and my makeup looks much better
