Photo Editing Required: Color Correction & Retouching

I need a skilled photo editor to help enhance one of my images. I’ve been trying to edit a picture i’m working on for my dad of his parents. His parents do not have any pictures together and are no longer here. All the photos I could find are very old and bad quality, I did my best to combine two of the pictures together but I can’t get the editing right or add a better background that is not white. I’ve added the pictures of my work & the pictures I used for reference.
The edits required include color correction and object retouching.

Color Correction:
- Adjust brightness and contrast
- Balance colors
- Enhance saturation

Object Retouching:
- Sharpening details

Ideal Skills:
- Expert in photo editing software (e.g., Adobe Photoshop)
- Strong eye for color and detail
- Experience with object retouching

I look forward to seeing your bids!
