I bought the Burning Heart palette too, I wish the Sweetheart palette had been available when I ordered, but I'll pick it up later along with Lumi.
I've used the Burning Heart palette twice since getting it on Friday. And I did a silly look just testing it out as well with all of the colors. I love it so much!!! On Saturday, I used flamepoint on my lid with the Hello Kitty Lucky Tom palette with creme de miel on the inner lid and Lucky tom on the outer lid and in the crease. It was so pretty, of course my family kept telling me how bright my eyes were, haha! Today, I'm using Poison Plum in the crease and outer outer corner along with Too Face Mess in a Dress in the middle and outer of the lid with Stars and Rockets on the inner lid, and Aromaleigh's Pandora on the tear duct. Both looks I did graphic black winged eyeliner.
Really, really liking them so much, it takes hardly no work at all to use them well as they are so pigmented.
