高级感圣诞节日主题插画

Nano banana prompt share🍌✨ 高级感圣诞节日主题插画，像这种简单画面简洁线条的插画，生成的质量几乎是完美的，再用工具转矢量就是高级的插图素材了。 A modern flat vector Christmas card illustration with thick black outlines. The background is light grey. At the top, bold typography reads "HOLIDAY VIBES". Below, a diverse group of three friends, including a modern cool Santa in a hoodie, are chilling around a funky Christmas tree. They have exaggerated proportions with huge hands and giant sneakers. The colors are mostly limited flat blocks of red, green, and blue, but accessories like the tree star, ornaments, gift boxes, and sneakers feature vibrant, psychedelic gradients (e.g., neon yellow-to-cyan, magenta-to-orange). The mood is relaxed, playful, and connected.
