Create an elegant and sophisticated hero image for a 2025 New Year celebration website, designed at a high resolution of 1920x1080 pixels with a 16:9 aspect ratio. The scene should feature a prominent clock or countdown timer, symbolizing the transition into the new year, rendered in a photorealistic style with detailed and lifelike elements. Use a monochromatic color scheme with shades of black, white, and gray to evoke a sense of timeless elegance. Highlight technology and progress by including modern gadgets, futuristic architecture, and innovative design elements that reflect sophistication. The lighting should be cool and calming, with soft blue hues that create a serene and refined atmosphere. Include the text "Welcome to 2025" in a sleek, modern font (e.g., Avenir), placed elegantly within the scene. The overall mood should be one of sophistication and anticipation, capturing the elegance of welcoming a new era.
