Child Face Photoshop Integration

I need a skilled Photoshop artist to seamlessly integrate my child's face where he is facing the camera in one outdoor photo onto another outdoor photo where we are facing the camera. I also need to expand the photo slightly on the left side. The purpose of this edit is to create a personal keepsake.

Requirements:
- Preserve background scenery
- Maintain original lighting and shadows
- Keep colors and tones consistent

Ideal Skills & Experience:
- Advanced Photoshop proficiency
- Experience with outdoor photo editing
- Strong attention to detail
- Ability to create realistic face integration
