Create a premium 3D grid of 12 square app icons arranged neatly on a clean white studio background. Each icon should look like a realistic modern version of popular apps including Spotify, Netflix, TikTok, Gmail, Google, Safari, App Store, Chrome, Clock, Calendar, Instagram, and Notes. Inside every app icon frame, place the same realistic man from the uploaded image, styled differently to match the theme and color palette of each app. Give him fashionable modern outfits, expressive poses, and interactions that creatively blend with the UI and environment of each icon. For example: relaxing inside Spotify with headphones, cinematic lighting in Netflix, trendy creator vibe in TikTok, casual aesthetic in Instagram, professional look in Gmail, etc. The icons should have a glossy 3D floating appearance with depth, shadows, reflections, realistic textures, and soft studio lighting. Make every square visually unique while keeping the overall composition cohesive and premium.
