Transform the subject into an ultra-realistic inflatable balloon head version of themselves. The face is fully puffed up like an air-filled latex balloon, cheeks expanded, lips enlarged and rounded, skin stretched smoothly with subtle latex shine and specular highlights. Maintain accurate facial features, skin tone, and expression, but exaggerate volume as if filled with air. The neck is replaced with a small tied balloon knot underneath the chin, with a thin string hanging down. Texture: smooth glossy latex surface, soft reflections, realistic balloon material tension. Lighting: soft studio lighting, diffused, minimal shadows. Background: pure white seamless studio background. Framing: centered, symmetrical composition, straight-on portrait. Ultra high detail, photorealistic, 8k resolution.
