A forest I've been working on using Treeit. Ground clutter are other assets outside of treeit. The tree atlases were made by creating leaf/branch variations in blender. I imported the mesh into Treeit, baked to texture and used them for the leaves. The trees were assembled in Treeit of course
Looks very cool, but the leaves looks very flat too, maybe you can try something with the shape of the branches, like cross with some deformation values
