見出し文字のない、丸い形のドット絵の雪だるまアバターで、8ビットのレトロゲーム風に作られた冬のホリデー用グラフィックです。濃い緑のシルクハット、鮮やかな緑のマフラー、オレンジの鼻をつけた笑顔の雪だるまが、雪の結晶が舞う紺色の円の上に立っています。文字は入っていないので、円の周りや下に名前、あいさつ、日付を自由に加えて、プロフィール画像やカードにできます。

Create a square Christmas profile avatar in crisp retro video-game pixel art. Center one original, cheerful snowman whose face is the clear focal point: two bright coal eyes, a small carrot nose, and a warm curved smile. Dress him in a simple little dark green top hat and a vivid green scarf wrapped around his neck, with two blocky scarf ends. Use bold, clean pixel clusters on a consistent coarse grid; sharp stepped edges, no antialiasing, no painterly texture, no photorealism. Set him against a deep midnight-blue night with a handful of distinct pale-blue and icy-white pixel snowflakes and sparse falling snow. Keep the background quiet so the face reads instantly at tiny profile-picture size. Use a compact circular composition: snowman centered and large, with hat, scarf and all important features comfortably inside the central 78% of the canvas so nothing is lost to a circular crop. Strong silhouette, bright face against dark blue, restrained retro palette, charming and upbeat. No text, letters, numbers, logos, border, extra characters, or additional Christmas props.
