Your World 1 background needs to feel calm and expansive while keeping the gameplay elements clearly visible, and that balance is what I’d focus on. I’d build the scene around warm planetary bands, a stylized orange storm, pale rings, and subtle depth from the stars and dust, keeping the pixel detail clean and the lower area uncluttered.
