Create a square 1:1 ultra-realistic YouTube podcast thumbnail portrait of a professional [Host Description], facing the camera with a confident and friendly expression. The host wears [Clothing] and sits in a comfortable chair at a wooden desk. Place a high-quality podcast microphone on a boom arm close to the host's mouth. On the desk, include a notebook with handwritten notes, a coffee cup, and a connected audio interface with visible cables. In the background, include [Background Lighting] to create a clean cinematic studio atmosphere. Use soft key light on the face, subtle rim light, shallow depth of field, 50mm lens look, f/1.8 bokeh, high-contrast professional color grading, crisp realistic detail, and a polished creator-studio aesthetic. Avoid real podcast logos, readable brand names, private information, extra watermarks, distorted hands, broken microphone hardware, unreadable accidental text, or low-resolution artifacts. Output aspect ratio: 1:1.
