Precise edit of image 1, output 4K. Turn every one of the five figures into a flat, solid, uniform dark charcoal-grey SILHOUETTE: no faces, no clothing details, no colours, no textures, no glowing eyes, just the filled outline. Keep each silhouette's exact outline, size, height, position and pose pixel-identical to the original figure (including the cape outline of the girl and the round plush shape of the small robot on the left). Keep the light-grey background, the horizontal height lines with their cm labels and the name/height labels under each figure exactly as they are. No other changes, no watermark.
