Generate a cinematic portrait poster based on the user-provided photo. The core concept is to use a massive, pure color field to support the subjects, who are nestled at the edge of the frame, both gazing up at the sky. Approximately three-quarters of the image consists of a clean, saturated, and uncluttered monochromatic field, resembling an infinitely distant sky, creating a sense of openness, longing, and the airy negative space of summer. The subjects occupy only a narrow band covering about one-quarter of the frame, leaving the vast majority of the space to the empty color field. The composition adapts to the aspect ratio: in vertical format, the subjects are positioned along the bottom edge in a low horizontal row, with the sky extending upwards; in horizontal format, the subjects are positioned along one side (e.g., the left) in a vertical row, with the empty color field spreading widely toward the other side (e.g., the right), where the text is placed. Regardless of orientation, the subjects and the text are always separated at opposite ends, with negative space remaining dominant. The shot must be a low-angle "worm's-eye view" taken from below: each character's head is tilted back, chin raised, neck stretched, with their face directed toward the top of the frame.
