Prompt: a poster for the post-apocalyptic thriller  "Jack's Legacy". The poster should feature the main character, Jack, in the center, with a stern and determined look on his face. Jack is a rugged, muscular man in his late thirties with short, dark hair and piercing green eyes. He is dressed in a torn leather jacket, worn jeans, and combat boots, ready for any danger that may come his way. In the background, there should be a desolate cityscape with a dark and ominous sky, suggesting the dangerous world that Jack must navigate. The poster should have a dark and suspenseful tone, with a color palette of greens, grays, and black to match Jack's eyes, hair, and clothing.
