Realistic-looking person (based on the photo provided, using the exact facial features without any alterations), positioned next to a giant vertical smartphone that simulates a digital billboard. The screen displays a real screenshot of the app interface [Instagram], provided by the user, shown with sharpness and proportions true to the original display. My User Name is : "Arnav" Caption: "You have done great Job" The person is shown full-body, with a natural expression and editorial-style posture, adapted to the type of app being featured (e.g., confident for LinkedIn, contemplative for Pinterest, casual or fun for TikTok, etc.). Styling and clothing should also reflect the app's vibe (e.g., creative casual, corporate, fashion, tech, boho, sporty, etc.).
