Business Photo Head Swap

I have a professional business portrait that needs a full head-with-hair replacement. The source image is high-resolution, and I already have the replacement head shot ready to supply as a separate file.

Your task is to blend the new head seamlessly into the existing body so the final image looks completely natural—matching skin tone, lighting, and background depth of field. No other edits are required beyond any subtle retouching necessary to make the swap invisible (color matching, edge cleanup, shadow consistency).

Please deliver a layered PSD for future tweaks plus a high-res flattened JPEG suitable for LinkedIn and print.
