Wedding Photo Composite Editing

I need one seamless, high-resolution image created from three photos I will supply. The main shot shows a bride whose wedding dress and bouquet both have to go; please replace them with a simple, regular white dress that matches the lighting and texture of the scene. The original background from this first photo stays exactly as is.

From the second or third photo, extract the elderly couple and place them sitting side by side in two chairs directly in front of the main subjects, mirroring the pose in my reference image. They should be smiling and looking at the camera so the final composition feels like a single candid family portrait. The second and third photo you get to choose from to see which fits naturally. The fourth file I’m sending is purely a style guide—use it to match color tone, depth of field, and overall realism.

Deliverables:
• Final flattened JPEG (print-ready, 300 dpi)
• Layered PSD so minor colour tweaks remain possible

Everything needs to look as if it was captured in one shot—no visible cut lines, consistent lighting and shadows, and natural skin tones. Let me know if you see any potential issues before you start so we can solve them together. Thank you!
