Help me create a product promotion video featuring a handsome male model showcasing the details of a short-sleeved shirt. The video should include descriptions without showing the cuffs, and only show the front view. The content style should be street-style photography, with the model walking forward facing the camera. The background should include a beach, a luxury car, and a cityscape. The model should wear jeans underneath. The video should have a high-end atmosphere, 4K high resolution, and rich detail display. Emphasis should be placed on showing product details, and each shot should not be too short
