Beauty lies in the eyes of the beholder ... and in the eyes of the person he/she is beholding too. Beautiful, expressive eyes are the first thing which hold our attention in the opposite sex. That's why, for centuries women have been using various means, be it liners, kohl, or shadows to make them appealing.
To give a dramatic effect, give them the shape of an arch. If your natural brows are straight, make an artificial arch just above them.
Start by applying the lighter shadow near the eyelash line. Now make upward strokes of this towards the brows, ending the shadow just below it so that a little space is created between the arch of the eyebrow and the shadow.
Take the darker shade and fill out this empty space with it by making strokes just below the brows, towards the outer face. Blend both the shadows together, to give a neat look. Twin shadows will make your eyes look large and also very striking.
Now, apply the liner to the lower lashes. In the lower lashes, a thin line should be made and it too should go beyond the outer corner of the eye. Unlike the upper line, it should be kept straight.
Becoming a good person will make you look beautiful more than any makeup, as is said "eyes are the windows to one's soul". So if you are beautiful inside, it is bound to get reflected outside through your appearance and personality.
