Try adjusting branch angle.  Big and small branches have the same angle and pattern–a “fractal” pattern.

Tree and roots are a fractal transport system, trapping carbon (black), releasing oxygen (red).

When carbon dioxide (CO2 black and red) touches leaves, it is used in photosynthesis. Oxygen (O2, red) is released from the leaves. Carbon (black) is converted to wood and sugars, or trapped in roots and soil, which helps fight climate change.
