Alien Ecosystem

I'm only concerned if I'm putting this in the right cathegory. I present VPF 1: the first of five moons orbiting a gas giant named Odin. VPF 1 is a moon made of 60% gold (Au), but this is a canyon of limestone, where greenish trees with sticky seeds grow. They shelter a predator that captures prey with its drool. One of those preys are Beach Disks, small flying animals who are leadered by the strongest male (this one has a scare on its wing). There's also a plant that travels at full speed with the help of an organic thruster, used to follow the sunlight. Though VPF 1 is quite a distance from it's only sun, the moon is warmed by steam from the soil and magma flows from below. More similar drawings coming soon.
