I felt the details are a bit off, and here I updated it:

1. Lower the water level. Instead of making the ground appear somewhat drowned, I wanted it to stand out more.

2. Fix the inconsistent art style. Actually, I like the barrel, but I think it looks more retro-ish than what I want.

3. Make the outline bolder and change the shape of the shadows.

4. I included animated waterfalls in four directions.

5. I included animated barrel, crate, and chest.

6. I included some grass textures.
