Watercolor illustration poster prompt, landscape 3:2. A warm watercolor poster of a cozy winter living room at night, centered on a glowing stone fireplace with lively orange and amber flames. Soft watercolor washes in warm orange, honey gold and cream melt into deep blue night shadows at the edges, a stack of firewood, a pair of knitted stockings and a steaming kettle on the mantel, a plaid blanket draped over an armchair, a sleeping cat curled on the rug, snowflakes drifting past the dark window. Loose watercolor brushwork with gentle bleeding edges and translucent color layers, flat graphic shapes with almost no fine detail, warm firelight as the focal glow, a wide cream border framing the poster, clean modern composition, no readable text, no logos, no watermark, rich painterly finish.
