Njgal it depends on the shape of u're face.. if u have a round face then u apply a deeper blush to the "hollows" of u're cheeks and finish-off with a shimerry blush on the apples of u're cheeks to create cheek-bones.
U shud also apply a small amount of bronzer/blush to u're temples.
Use a eye-shadow 2 shades darker than u're complexion for contouring u're nose.. apply it on the sides of u're nose and use a "bone-white" shadow and go down the bridge on u're nose.
For people with a long nose.. u need to apply some to the tip of u're nose..
To make u're jawline more prominent apply u're bronzer to bottom part of u're jawline.
Please keep the shape of u're face in mind before contouring.. the one mentioned above is for round/oval faces.
