Maintain their original poses and outfits exactly.Add retro 8-bit pixel art Pokémon characters throughout the scene: Bulbasaur, Charmander, and Squirtle standing in the foreground on the stairs; Mew, Geodude, Butterfree, Charizard, and Pikachu floating in the air around them. The pixel art style should be colorful, nostalgic, and clearly distinguishable from the photorealistic background.
