Prompt: A single large three-dimensional English letter “A” formed entirely from dense clusters of soap bubbles, fully volumetric and floating as a sculptural 3D object. Thousands of translucent bubbles of different sizes merge together to create the letterform, with highly detailed thin-film surfaces, iridescent reflections and subtle rainbow highlights visible across the bubbles. The silhouette of the letter remains clean and recognizable, while the surface feels soft, airy and complex. Realistic transparency, glossy reflections, delicate light interaction, studio macro aesthetic, soft but controlled lighting, light grey background, ultra detailed 3D CGI render, hyper realistic bubble structure, centered composition, no text, no extra elements.
