Create an experimental 4:5 portrait where a single woman's

Create an experimental 4:5 portrait where a single woman's face appears both sharp and blurred — one half perfectly detailed and recognizable, the other half dissolving into soft watercolour-like blur, creating a dreamlike reflection effect. The two halves meet at the center of the face. Soft neutral background, delicate colour gradient. Conceptual fine-art portrait photography, 8k, no text.
