Searching for vegetation on a new planet.

Hey everyone! I haven't been here for a long time, but every cloud has a silver lining. I'm back with more exciting ideas.
I've started creating my own project in which we'll leave Earth and travel to distant corners of space.

Today, for starters, preliminary designs of vegetation on that planet, some sketches, and a colorful concepts of a windy tree with huge leaves that feed on pollution.
Which option do you like the most 1-8? And what color scheme should it be in to make it more alien and unearthly?
