Acorns are made with separate meshes in a separate collection. Acorns can be turned off, removed, and each acorn can be moved. The leaves do not have curved geometry, but they are made with smooth planes per 2 polygones. For the foliage texture, I personally photographed the leaves. In total, the model uses 3 unique photographs of the leaves. Everything is packed into a .blend file. All the trees in the renders are the same: one single tree was used at different viewing angles and with different proportions. The default height is 21.5 meters.
