Minimalist Animated Face Creation

Animated Character Face — 4 Emotional States (Lottie/SVG)
I need a simple animated face.
The character is minimal by design: only the facial features (eyes, eyebrows, mouth) animated on a fully transparent background.
No face shape, no skin, no textures.
Think of it as animating 3 graphic elements floating in space.
The 4 states needed:

Idle (slow blink, subtle movement)
Listening (eyes slightly wider, attentive)
Thinking (eyes shift, one brow raised)
Speaking (mouth open/close loop)

Technical requirements:

Canvas: 800×800px, transparent background
30fps, all 4 states as loopable segments on a single timeline
Output: Lottie JSON or animated SVG — must be controllable via JavaScript
Include original project file (AE, Rive, or equivalent) + MP4 preview

Tool is your choice — After Effects + Bodymovin, Rive, SVGator, or anything that outputs Lottie JSON or JS-controllable SVG.
