Plan:
Not sure how long I plan this to be, maybe 15-20 seconds.
First part is basically what you see here but with more varied movement
Second part is him looking towards Mercy.
Mercy still looks for like 2 seconds down, then suddenly pans up towards the camera, then she does some facial expression that i don't know yet.
Then the camera pans back down and restart the looping animation.
Bonus:
Here's a preview of an older itteration of the animation but fully lit in Blender's Eevee Render Engine
