“M”是一张经典节日风格的字母组合卡片，中央只有一个金色字母。带衬线的大写字母呈拉丝金属质感，被一圈圆形松枝花环环绕，花环上有四簇红色浆果和几片叶子，背景为奶油色。你可以把首字母换成自己的字母或组合字母，并根据姓名、家庭或活动调整颜色和绿植装饰。

Create a classic, clean Christmas profile avatar on a warm, solid cream background. Square composition designed to remain instantly recognizable when cropped to a circle and viewed at tiny phone-thumbnail size. In the center, place one full, balanced circular wreath of deep green evergreen sprigs, with a few distinct rich red berries spaced evenly among the leaves. Inside the wreath, render only the exact uppercase letter “M”, large and perfectly centered, in elegant gold. Use a refined, moderately high-contrast serif capital with graceful proportions, crisp serifs, clear open spaces, and sturdy strokes that remain legible when small. Give the letter a restrained satin-metallic gold finish with a fine warm highlight and subtle dimensional shadow, not glitter or excessive ornament. Keep the wreath foliage clean and graphic, with softly layered needle shapes and restrained natural shading; berries are glossy but simple. The wreath and letter sit comfortably within the central 76% of the canvas, leaving a generous cream margin so nothing important is clipped by a circular app crop. Warm, even light, subtle soft shadows, crisp edges, polished but understated. No extra text, no additional Christmas motifs, no border, no busy texture, no watermark.
