Seasonal Phone Wallpaper Generator — Holiday 4K

A vertical 9:16 seasonal phone wallpaper for Christmas: warm string lights woven through pine branches. Output resolution: 4K ultra-high definition, vertical portrait orientation, designed for a phone lock screen. Composition: subject anchored in the lower third, framing upward along the edges; upper third kept simple and low-contrast so the clock stays legible; lower quarter darkened so home screen icons remain readable. Lighting: warm string lights as the only source — warm light pooling around its source and falling off into deep shadow, giving the wallpaper natural depth without clutter. Bokeh: large soft glowing orbs filling the blurred background. Detail at 4K: individual pine needles and the glass of the nearest bulb sharply resolved in the focal plane, everything else softening into atmosphere. Colors: warm gold, forest green and deep shadow — limited to three tones so the wallpaper stays calm behind app icons. Atmosphere: fine falling snow catching the light. Finish: subtle film grain, slightly lifted blacks for a warm photographic feel. Quality: 4K ultra-high definition vertical seasonal wallpaper. No text, no watermark, no logos.
