A 2x2 grid of colorful cartoon-style character avatars displayed on a bright blue background. Each avatar is placed inside a circular frame with a slightly darker inner background and a brighter border top-left red, top-right blue, bottom-left green, bottom-right yellow. Each character shows a cheerful, friendly face with smooth 3D shading, soft lighting, and clean vector illustration style. The composition is vibrant, modern, and ideal for a mobile game player selection screen.*修改网格数量比如 2×2 改成 3×3 可以一次得到更多结果，这些预览是用的 3×3，要让头像背景和边框符合提示词设置的话就用 2×2。
