These textures are amazing, Morain. I have used them in perhaps an unorthodox way for my game idea. The textures give my card appearances a unique look that I like.
My game is a live service incremental card strategy game called LootRNG. I have credited you here: https://lootrng.com/credits (also in the game main menu).
I'm working on converting it into an app that will be available here when done:
