Use movement to clarify the emotion
Good loops show one idea: waving hello, laughing harder, crying dramatically, shaking no, celebrating, or blinking in disbelief.
Avoid long scene animation
A sticker is not a video clip. Keep the motion focused on a face, hand gesture, bounce, or caption effect that still reads quickly.
Create static and animated versions
Some chat moments need movement, while others work better as quiet static stickers. A mixed pack can satisfy both search intent and real usage.
