Moderate Body Reshape for Social Media

I am seeking a skilled photo editor to transform a photo for use on social media. The primary requirement is to make the person in the photo appear moderately thinner, with a focus on altering the waist and overall body shape. I'm looking for adjustments that will be noticeable, yet still maintain a sense of authenticity for the viewer.

Ideal skills and experience:
- Expertise in advanced photo editing
- Proficiency in Photoshop or similar software
- Prior experience in body reshaping and retouching
- Ability to preserve the essence and authenticity of the original image while making significant alterations
- Strong attention to detail and an understanding of human anatomy to ensure realistic results.
