テキストのないハロウィンのスマホ壁紙で、満月を横切るほうきに乗った魔女を、暗く夢のような雰囲気で描いています。魔女と猫、小さなコウモリの黒いシルエットが、光るクリーム色の月に浮かび、下にはネイビーの暗いモミの木と枯れ枝が並びます。上部の何もない夜空には、自分のタイトルや名前、日付を入れられ、色もテーマに合わせて変えられます。

Create a finished 9:16 vertical Halloween phone wallpaper in a crisp, layered silhouette style. No text, lettering, symbols, interface, phone frame, clock, or icons. Reserve the upper 40% as a calm, nearly uniform deep midnight-indigo sky for the real lock-screen clock: keep it dark, low-detail, and free of bright highlights. Place a large pale, softly textured full moon entirely in the lower half, centered slightly right, its lower edge partly screened by the treetops. A clearly readable black witch silhouette rides a long broom diagonally across the moon, traveling from left to right; show a pointed hat, flowing cloak, broom bristles, and a compact cat silhouette perched behind her. Keep the witch’s silhouette clean and distinct against the moon. Along the bottom third, layer a sparse spooky forest in near-black silhouette: uneven firs, a few crooked bare branches, and low rolling ground, with open gaps rather than dense detail. Add a few tiny distant bats near the moon only, away from the clock zone. Palette limited to midnight indigo, blue-black, muted violet, and cool ivory moonlight; no orange hotspots, gore, blood, or gradients bright enough to compete with the clock. Use clean cut-paper-like silhouette edges, subtle fine-grain night-sky texture, restrained moon surface detail, and soft cool rim light along select treetops. Keep all important forms comfortably within the canvas edges. The moon and flying witch are the focal subject in the lower half; the upper sky remains a broad dark negative-space zone.
