I'm looking out the window at trees. I see hundreds of shaded of green, not just on different trees. The apple has about a dozen brown leaves and a dozen that are yellow. One leaf is yellow on one half and green on the other. Bryce only allows you to apply the same color to all leaves. The tree splits about 6 feet off the ground. The left hand branch is 1/3 the diameter of the right. The right makes a bend about 2/3 up without branching. If Bryce would allow you to generate single leaves to color differently, control branching, or turn roots off so you could stick two trees together as one you could fake the messiness of nature.
