天井に風船

Use the uploaded image as the only source of identity and environment. Preserve the subject, face, pose, clothing, camera angle, buildings, and lighting exactly as they are. Add a very large number of party balloons completely covering the ceiling or upper area of the scene, forming a dense balloon ceiling. Balloons should be tightly packed, overlapping, and layered, with slight variation in size and color, and some appearing slightly deflated or pressed together. All balloons must follow realistic perspective, depth, and lighting, sitting naturally in the space. Do not cover or obscure the subject's face. Maintain the original mood and color balance. No fireworks, no text, no glow effects, no environment redesign. Style: ultra-realistic, candid celebration photography.
