I used these as items in a game of mine. I gave you credit even though it's CC0 and linked back to your OGA profile. I also used your adventurer kit images for some stuff too. Actually, after looking over all of your stuff, I should've used some of your paper textures, because I think they're better than some of the ones that I ended up using. Here's the game then if you want to check it out: http://gamejolt.com/games/adventure/squam-a-dungeon-and-its-victim/37831/

I used this for my Red Key item in the game Celestite for the recent OGA game jam: https://itch.io/jam/opengame-art-game-jam/rate/162467
