Realistic Tattoo Photo Overlay

I need help combining several photos to present a project to a tattoo artist. The final image should have a realistic style.

Requirements:
- Overlay Technique: I want you to overlay one photo on another.
- Realistic Style: The combined photo should reflect a realistic style.

Ideal Skills and Experience:
- Proficiency in photo editing software
- Strong artistic sense for realistic imagery
- Experience with photo overlay techniques

Please provide samples of similar work. The finished project should wrap around my forearm.
