For a living room full of curves, this Art Nouveau portrait brings the check. Mucha's flower-crowned woman softens hard corners and gives painted plaster walls something romantic to lean into. The cream, dusty pink and deep green do the heavy lifting — warming dark woodwork without going heavy, and lifting a quiet neutral room with a hit of decoration. Hang it above a velvet sofa, a writing desk, or in a hallway where it greets you head-on. It sits beautifully near walnut, brass and linen, and earns its place beside small antique mirrors or a marble-topped console. Avoid stacking it next to busy modern graphics or bright primary-coloured posters — they'll squabble for attention. Let this one lead.
