The initial one is using a dark base on 2 sides of the forehead, on the brow bone, on the cheek bone, on the chin and about the lips. This contouring is using pink pigment to the cheek bone to the nose and a bit to the chin. This is a direct where you must place the foundations, and after that all you require to do is to merge them jointly.
On the second contouring i used only dark and light foundation. Add shading to the face perimeter, to nose, to brow bone, lips and forehead.
The third, is using fewer dark for contouring, put in it to the two sides of the for ahead, to your nose, and the chin. You can put in also only a bit over your upper lip.
