Using SpeedTree to Match Concept Art (Time-Lapse)

We start with concept art that we place in our scene and create a tree from scratch (textures and auxiliary scene meshes are pulled from our library).
All features shown, except seasonal change, are available in the $19/month Unity 5 and UE4 subscription Modelers.
Time-lapse speeds vary from 2x to 10x throughout. Some sequences are shown out of order.
