Mouth Closure on Side Profile Shot

I have a side profile photo of me with my mouth open, and I need it to be photoshopped so that my mouth appears closed. The final look should be natural and realistic, so it blends seamlessly with the rest of the photo.

I do have a reference photo that shows how I want the closed mouth to look.

Please note, I only require this specific edit. No other alterations to the photo are needed.

Ideal Skills and Experience:
- Proficient in Adobe Photoshop
- Experience in photo editing for natural and realistic outcomes
- Good attention to detail
