12月24日の日付が入ったスマホのロック画面「9:41」、ゆるい水彩の冬景色によるクリスマスイブの壁紙です。濃紺のサンセリフの数字と日付が白い紙の上にあり、その下に明かりのともる丸太小屋、雪をかぶった松、霞んだ青い山々の雪景色が広がります。時刻、日付、あいさつを自分のものに変えたり、小屋の景色の色を好みに合わせて変えたりして作り直せます。

Create a finished 9:16 Christmas phone lock-screen mockup, shown straight-on as it appears on a modern smartphone. The phone fills nearly the entire canvas, with a slim dark rounded bezel and the full screen clearly visible. Inside the screen, keep the upper portion open as warm-white cold-press watercolor paper with generous breathing room for legible interface text. Set the date above the clock in small, clean, dark slate-blue sans-serif letters: “December 24”. Below it, make “9:41” the prominent lock-screen clock, large and crisp in a restrained modern humanist sans-serif, dark slate blue, evenly spaced and highly legible. Preserve the text exactly; add no other words or numbers. A tiny simple lock symbol may sit above the date; use only minimal, familiar status and bottom-corner camera/flashlight icons, with no labels. In the lower portion of the screen, paint a quiet snowy pine forest in loose hand-painted watercolor: layered slate-blue and sage-green pines, soft white snow, pale blue rolling ground, and one small timber cabin nestled among the trees, its windows glowing warm golden ochre. Let the scene fill the lower half of the screen and fade softly into untouched paper at its edges. Use wet-on-wet washes, gentle pigment blooms and granulation, fine ink-free brushwork, visible cold-press paper grain, and a few white gouache snow dots. Keep the result recognizably an illustrated watercolor Christmas wallpaper, not a photorealistic landscape. Soft cold winter daylight, muted winter colors, warm windows. Keep the date and clock unobstructed and readable; no extra lettering, logos, watermark, or decorative frame beyond the phone itself.
