Urgent Necklace Pendant Edit

I need to edit a photo for a client who was a victim of the Texas floods; they lost their home, everything and has been in the hospital. The photo is needed ASAP. I do not have the original photos with me. I have them back at home on an external. I wish I did! She contacted me while I am out of town. I want to make sure their sweet dog is looking at the camera; they lost him in the flood. I am trying to make sure the best photo is shown so if I need to switch a person, dog head etc. I am just in the thick of the emotions on these photos and others I am handling I just could use someone to help decide also which to use etc There is one more photo but it won't load. Again, not to use all of them. The photo with the black dress I think has the sharpest shot of it. If you choose to do this project then I can share the other photo to see which you think is easiest to work with an also the best overall.

Requirements:
- Replace circle pendant on client's necklace using my provided image. The heirloom pendant needs to be sharper.
- Optionally, make the green in the trees deeper.
- Possibly switch the dog's face if needed.

Ideal skills and experience:
- Proficiency in photo editing software (e.g., Photoshop)
- Attention to detail
- Experience with jewelry and animal face replacement in photos
- Ability to work quickly and meet tight deadlines

This also needs to be kept private.
