[FACE — left 40%] [TEXT — right 60%]
[ ELEMENT / ARROW pointing at text ]
[OPTION A — left 50%] | [OPTION B — right 50%]
[ VS or arrow in center ]
[ RESULT / OUTCOME (large, center) ]
[ Small "before" image + title text ]
[ LARGE NUMBER (50% of thumbnail) ]
[ Short text + face in corner ]
GOOD text overlays:
✅ "I Was WRONG"
✅ "$10k in 30 Days"
✅ "DO THIS NOW"
✅ "The SECRET Method"
BAD text overlays:
❌ "In this video I explain how to make money online using affiliate marketing"
❌ (no text — loses viewers who watch muted or on small screens)
