Please help me! I am DeepAR beginner

I’m trying to create an interactive face filter for web compatible videos, but I don’t know how to start from scratch.
This is the requirements for the filter:
Filter Design – Fox Eye / Cat Eye Simulation
:small_blue_diamond: Outer Eye Corner Lift
Subtly rotate the outer corners of the eyes upward (approx. 5–10 degrees).
Use face mesh deformation or eye anchor point adjustments for a natural, lifted look.
:small_blue_diamond: Eyebrow Tail Lift
Slightly raise the tail end of each eyebrow (outer third).
Use 3D mesh warping or positional shifts to simulate a thread lift effect.
:small_blue_diamond: Temple Smoothing (Optional)
Apply light smoothing to the skin near the temples and outer eye area.
Use a subtle shader or texture blend to simulate mild skin tightening — avoid excessive blurring or artificial look.
:small_blue_diamond: Wrinkle Blurring
Softly blur or fade fine lines and wrinkles around the outer eyes and temples.
Use light blur or texture blending — wrinkles should be nearly invisible but not unnaturally erased.
:small_blue_diamond: Symmetry
Ensure both eyes and brows are affected evenly.
The filter should automatically align and adapt to different face shapes and positions
