Recolor only the background of image 1 to a flat, neutral, mid-grey studio backdrop (pure neutral grey, no blue tint, no warm tint), with the same soft floor shadows. Keep everything else exactly the same: the same man, the same face, beard, cap, clothes, the same layout with the large close-up portrait on the left and the small front and back full-body figures on the right, same sizes and positions, same lighting on him. Photorealistic. No text, no labels.
