Reference
Since the ferris wheel is huge, if other things are too small in the scene, the overall look will be unbalanced. So we decided to put giant plants into the scene to keep the balance, such as the mushroom-like plants, or the glowing plants that can float in the air in Avatar. Also it is a way to create an atmosphere of an alien planet.
There are flowers that can release glowing pollen, this could be done with particles animation.
There could be more plants on the ground with unusual shapes.
The ferris wheel should be sci-fi style and the material is metal, so the texture is more like the metal used on rockets.
