一张专业的、高端的平面设计广告构图，置于纯白色画布上。画面中央是一个完美对称的、大型实心圆角正方形（非空心边框）。正方形的整个内部填充了平滑、鲜艳的渐变色，从 [Top-Left Color/Hex] 渐变到 [Bottom-Right Color/Hex]。 一位 [Description of Character] 被放置在画面中，其躯干底部与正方形的最底边完美齐平对齐，下方没有留下任何明显的彩色边框。至关重要的是，人物及其衣物保持自然、真实的色彩和纹理，由专业的影棚灯光照明，且灯光独立于背景渐变（防止其皮肤或衣物出现任何偏色）。 他们牢固而真实地握持着 [Product Description]。关键在于，他们的头部和头发突破了正方形的顶部边界，部分与白色背景重叠。他们的手和 [Product Name] 也突破了侧面边界，营造出强烈的 3D 突破效果，延伸到白色画布上。 排版布局：顶部，在正方形上方清晰的白色空间中，留有明显间隙，是 [Font Style] 品牌文字“ [Brand Name] ”，颜色为 [Top Text Color]。在右下角，直接叠加在正方形内部的渐变色之上，是一小段纤细、简洁的 [Bottom Text Color] 描述性文字：“ [Slogan/Tagline] ”。 灯光是 [Lighting Type: e.g., Sharp/Soft] 的，清晰且具有商业感，强调了主体和产品的纹理。
A professional high-end graphic design advertisement composition on a pure solid white canvas. Centered is a perfectly symmetrical, large solid rounded square (not a hollow frame). The entire interior of this square is filled with a smooth, vibrant color gradient fading from [Top-Left Color/Hex] to [Bottom-Right Color/Hex]. A [Description of Character] is positioned such that the bottom of their torso is perfectly flush and aligned with the very bottom edge of the square, leaving no thick colored border visible beneath them. Crucially, the person and their clothing maintain natural, realistic colors and textures, illuminated by professional studio lighting that is independent of the background gradient (preventing any color cast on their skin or clothes). They are firmly and realistically gripping [Product Description]. Crucially, the top of their head and hair break the top boundary of the square, partially overlapping the white background. Their hands and the [Product Name] also break the side boundaries for a powerful 3D breakout effect, extending onto the white canvas. Typography Layout: At the top, in the white space distinctly above the square with a clear gap, is the [Font Style] brand text '[Brand Name]' in [Top Text Color]. In the bottom-right corner, layered directly on top of the gradient inside the square, is a block of small, thin, clean [Bottom Text Color] descriptive text: '[Slogan/Tagline]'. The lighting is [Lighting Type: e.g., Sharp/Soft], crisp, and commercial, emphasizing the textures of both the subject and the product."
