T-Shirt Smoothing & Facial Edit

I need some photo editing done on a picture of a male wearing a tee shirt. The edits will require smoothing out a specific area on the shirt/chest region, alongside replacing the smile on the subject with a different one.

Ideal skills and experience for the job:
- Proficiency in photo editing software (e.g., Adobe Photoshop)
- Attention to detail
- Ability to follow specific instructions
- Experience in facial editing and clothing smoothing
