I wanna add that it's allso important to use the right blushcolor, for example: fleur power not a good one on itself,it's way to pink (IMO) to use to shape the face. I love strada, buff, spice, tenderling and cubic a lot for this use. use it with a blush brush or a kabukibrush. When you are ready to apply, suck in your cheeks and apply in just above the "sucked-in line" (lol I can find th eright words) and when you apply, folow the shape of your cheekbone and make a bit of a C-shape (a c on it's side that is), start at the temple and move towards the apple of the cheek.
To add a bit of blush on top of this, you can use a more pink blush like fleur power of sterio rose MSF, and apply it on the apple of the cheek.
I made a simple drawing on a pic of me, I hope it makes sense
the brown line represents the "shaper" to make your cheekbones stand out more, and the red circle represents the blush.
I must advice to do this with a BLUSHBRUSH and not the pencil brush, or you'll like like an idiot, hahaha.
