When Autumn Comes

Just a disclaimer, I only worked on this for like 3 hours, so it's not even a game, and there's just a small animation. Everything's quite rushed. I would appreciate feedback on the artwork though, as I've never tried like a watercolor style out.

This was how the real game was supposed to be:

It was supposed to be more of an atmospheric game, where the player has to try to protect things from fading, like leaves, animals, etc. But soon, the player is unable to stop the fading, and then everything fades away, leaving a barren landscape. Finally, the last leaf on the tree falls, and then the camera starts to follow it. It shows the journey of the leaf, letting the wind carry it to the ground, until it grows to a whole new tree, and the animals and other life come back to it and use it for shelter.
Unfortunately, I didn't have time for all of this, so it's been shortened to a simple animation.
