Photo Restoration for Memory

I need a photo of my late aunt and her husband altered. Her ex-husband needs to be cropped out, and I would like a happier background for her. This photo is for her children, so it's important it looks natural and not fake.

Requirements:
- Crop out ex-husband
- Add a happier background (nature preferred)
- Maintain a natural look, not fake

Ideal Skills & Experience:
- Photo editing proficiency
- Experience with background replacement
- Attention to detail for realistic results
- Ability to work with provided reference photos

Additional Notes:
- I have other photos of my aunt to guide the editing.
- The overall mood should be happy.

This project is dear to my heart, and I appreciate your sensitivity and skill.
