EDIT THIS PHOTO. Keep the man exactly as he is — same face, same hair, same expression, same clothes (white t-shirt, open black overshirt, thin gold chain), same pose and framing.
Completely REMOVE the home studio: remove the window, the blinds, the microphone, the stand, the acoustic panels, the walls and the desk. Nothing from the original room may remain.
Replace the ENTIRE background, from the left edge to the right edge and from the top edge to the bottom edge, with ONE flat solid chroma-key green color #00B140. Every pixel that is not the man must be this exact pure green. No shadows, no gradient, no vignette, no light falloff, no texture, no window light, no objects.
Even soft front lighting on him, clean sharp edges around the hair and shoulders, no green tint or green reflection on his skin, hair or clothes. Photorealistic, vertical 9:16. No text, no logos.
