Bronzing/blush help?

So, I just picked up this contouring blush/bronzing powder duo from Elf (my first bronzer ever) and I'd like to use it for the first day of school tomorrow, as I'm going to wear foundation (I have a lot of acne and would like it covered) and don't want to look washed out. Can someone explain to me where to use it exactly, so I don't look like a clown? I have no idea how to use this, I have a small stipple brush to use it with (also from elf, I just grabbed it really quick as I was in a hurry). 
That's what it looks like. I need to learn how to do this fast, so thanks for any advice!
