Realistic Personal Picture Mock-Up

I’d like a skilled editor to merge an additional picture into my existing photo so seamlessly that no one can tell it was ever altered. The piece is strictly for personal use, yet I still expect a polished, studio-quality result. Everything must remain true-to-life—lighting, shadows, colour, and perspective should align perfectly for a fully realistic finish.

I will share the base image along with the extra element I want incorporated as soon as we begin. Feel free to use Photoshop or any comparable tool, as long as the outcome looks natural.

Deliverables
• Final mocked-up image in the original resolution (JPG or PNG)
• Layered, editable file (PSD or similar) for any future tweaks
