I created these trees recently for a job at Daz3D/Tafi.
Using photographic references, these trees have been carefully detailed with imperfections, wounds on the trunks and creative shapes on each item.
I used ZBrush for details and retopology of the meshes for a cleaner object with no loss of quality.
With extra accessories with FiberMesh technology and special plug-ins, they made these trees even more beautiful.
