Behind the girl and the cat, the universe expands, with a cinematic style of planets as the background. The surface of the planets has crepe-like textures, and in the planet's atmosphere, various simple shapes such as circles, triangles, and squares create a visual composition. The space, which serves as the background for the planets, should have a violet hue with a gradient of white and pink from the Horsehead Nebula appropriately combined. The space is filled with stars, emphasized in white and bright yellow, to enrich the details of the artwork.

To enhance the sense of depth and liveliness, apply textures and patterns on the planets. Add diverse textures and patterns to various shapes and complex elements to anchor the focal point of the artwork and create a harmonious rhythm throughout.

Consider these modifications to reconstruct the artwork, and if necessary, employ additional techniques and creative knowledge to craft a piece with a higher level of completion and richness in expression in a cinematic style.
