现代3D极简高端人物宣传海报

Create a modern 3D promotional poster using my uploaded photo as the facial reference. Preserve my exact facial features, skin tone, and face shape. Place me sitting confidently on a stylish oversized dark black sculptural chair, wearing dark black sweatshirt and sweatpant outfit with white sneakers. Use a clean gradient black background with soft abstract 3D shapes, floating glossy spheres, and subtle studio lighting. Add large, bold white typography behind me that reads "JULY", with elegant handwritten text above it saying "Welcome to". Do not include any other text, logos, dates, watermarks, or branding. The composition should be minimal, premium, vibrant, and social-media-ready with a luxury graphic design aesthetic, ultra-sharp details, soft shadows, photorealistic quality, and 8K resolution.

使用我上传的照片作为面部参考，创作一张现代3D宣传海报。保留我精确的面部特征、肤色和脸型。让我自信地坐在一把时尚的超大深黑色雕塑椅上，穿着深黑色运动衫和运动裤套装，搭配白色运动鞋。使用干净的渐变黑色背景，带有柔和的抽象3D形状、漂浮的光泽球体和微妙的演播室灯光。在我身后添加大而粗的白色文字，写着“JULY”，上方有优雅的手写体文字写着“Welcome to”。不要包含任何其他文字、徽标、日期、水印或品牌。构图应简约、高端、充满活力，并适合社交媒体，具有奢华的平面设计美感、超清晰的细节、柔和的阴影、写实品质和8K分辨率。
