Hi, are you aware that the current license means the assets can't be used in commercial projects? CC-BY-SA4.0 is probably what you're after.
You might remember, I commented on your other work (portraits) last month about CC-BY-SA being bad for games, I've since learned that thankfully that's fine for video games, but the NC (non-commercial) versions of CC-BY and CC-BY-SA definitely put a hamper on ambitions :)
Once again, thanks for creating and making available such beautiful assets
