Héroes felinos retro con máquina del tiempo y torre del reloj

Stylized retro movie poster illustration for 'Back to the Future' featuring cats. An eccentric wild-haired white cat (Doc Brown) in a silver suit stands next to a DeLorean time machine with glowing wheels. A young cool orange tabby cat (Marty) wearing a red life vest stands on a hoverboard holding an electric guitar. Background features a dramatic clock tower struck by lightning. 1980s aesthetic, vibrant colors, grainy texture, dynamic composition, nostalgic sci-fi vibe.
