创作一张比例2:3的竖版万圣节手机展示背景。紫色无缝墙地，橙铜色与浅紫色作为辅色，圆润哑光立体渲染。中央竖立一部大号手机，细铜色圆角边框，顶部装紫色波浪边遮阳棚，屏幕为完整、均匀的奶油白空白，不显示界面。 手机立在两级椭圆台座上，上层为橙铜色、下层为紫色，前缘清楚。左后方只放一个紫橙色小扩音器，架在小方台上；右后有两只大小不同的紫色礼盒，橙色缎带，下面垫几何方盒。 右前侧聚三只深浅不同的紫橙气球，左前放一只高瘦笑脸南瓜与一只小紫南瓜。少量圆形纸屑沿地面边缘散开。主光柔和，铜边与气球有克制高光。 让屏幕保持最大、最干净的展示区，前景道具不要遮住屏幕。不要文字、字母、应用图标、商标、水印、人物或外部边框。
