Fix Unity FBX Animation Files

I need a skilled animator to refine two FBX files in my Unity project, one male and one female, to ensure the animations match the original video provided. The goal is to enhance movement accuracy so that the steps appear natural, and the characters convincingly perform a dance.

Key Requirements:
- Adjust the FBX animations to closely align with the reference video: https://vimeo.com/594115144
- Ensure that the steps look realistic and the characters' movements are fluid and synchronized
- Confirm that the characters are correctly interacting with the environment, touching the ground as they should and interact with each other.

Ideal Skills and Experience:
- Proficiency in animation editing
- Experience with FBX file manipulation and animation refinement
- Strong attention to detail to achieve realistic movement accuracy
- Ability to work with video references

Please review the provided files for context:

I'm looking forward to seeing the animations come to life with your expertise!
