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 green sculptural chair, wearing dark green sweatshirt and sweatpant outfit with white sneakers. Use a clean gradient green 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.
