I made this stylized toon tree model ... with some sinuous shapes :)   But still with a focus on a lower polygon, or even mobile devices to adjust a simple shader on the game engine. The textures were made by me. The textures of the leaves of the trees I used textures that I already sent to OGA, and can be found here (https://opengameart.org/content/stylized-textures-of-shrubs-and-tree-tops). The original .blend file is like the tree divided into parts, to facilitate cutomisation and editing if you prefer. I also put .fbx files to use in other game engines (I tested them on unity). And to facilitate customization or LOD in some situations, I put them in different approaches. And the textures to use in game engines (again I tested them on unity) are in a .zip file. Only simple (diffuse) textures. I hope it will be useful in someone's project.
