A quiet museum gallery with simple framed artwork shapes without text, polished floor, and soft overhead lighting. Clean neutral palette with restrained wall and floor contrast. Keep the center area visually uncluttered with simple forms and open space behind layered foreground subjects. No characters, no text. Mostra altro
