Ideas for getting makeup?

Hey r/makeupaddiction, I just got a $40 Sephora gift card, and I have no idea what to do with it. I have green eyes, some acne ( althought not very severe ) oily skin, and a heart shaped face. I also love powder foundation, what are some really good brands? As for what I already have, I don't have a lot of makeup, just some basic drugstore stuff. Thanks!
