For my 3D Emote, I wanted my character to do more than a simple action like waving. I was inspired by bodybuilders, and how they have distinct poses that they make when flexing, so I decided my 3D emote would be a person flexing in three different positions. If there were anatomically-correct muscles on this 3D model, then different distinct muscle groups would stand out during each of the three flexing positions.
The first position was the most difficult to animate, because when the person crouches while flexing, I had to shift the model of the person down as well so the feet would remain planted on the ground at all times. Otherwise there was a point where the person would float in the middle of the emote. To finish the animation, I added a simple wrestling ring background and lights above the character to help add to the story of the emote.
