This is a free flower, rock, leave and grass pack, all textures are royalty free
"royalty free" does not mean you can release it under an open source license, especially not CC0.
really? i thought that meant the textures have no ties to the original maker and therefor are copyright free, and anyway its only the rock and flower textures which i got off a copyright free website
Nice work! Thank you for sharing! I'll credit you when I use it.
