I picture the trees on Planet Zi forming root networks. I was picturing the neural network of Pandora from Avatar when I was illustrating these, and considered making them phosphorescent, but thought it would be too derivative to be worth the effort.

It's been a couple weeks, so I'm posting another progress update. Worked on the main weapons and legs for the #battlecougar redesign. And the rear leg and booster for the #commandwolf, and the forest background. I gave the trees a network of roots to make them different from Terran trees.
