Nice image, I really like those aspens! I've spent a lot of time around aspen colonies, some of the oldest living organisms on the planet. Quite often the terrain and snow accumulation pushes and distorts the young 'shoots' and with the snow melt their heliotropism resumes a 'straight' growth, often distorted again by subsequent seasonal snow. So, yeah they'll grow straight up, but Nature likes to mess around with things.
Speedtree has to be one of the best designed programs I've ever used; from the beautifully functional UI, to the incredible output, and the sheer creative freedom that makes the program just plain fun to use (yes, Fanboy language...)
Always a pleasure to see you create an Alpine scene!
