I made this stylized texture. They are textures of branches and leaves of trees, or shrubs, in which to adapt better in your good projects. I tested it as a 3D billboard texture in the Unity3d terrain, and I found the result interesting:)

I hope it is useful. Modify it, if you prefer, to better adapt to your needs. You don't need to credit me. Feel free to let me know if you use it on any project, but only if you want to.
