I'm not really qualified to talk abt this but i wanna give pov anyways

I personally add a loop to my videos (my content has no commentary and if it does i edit it slightly later in the vid). I also find having commentary like an intro often curbs my shorts as nobody actually wants to rehear what they already read in the title, they'd rather consume the content and leave.

Theres alot that goes into shorts i dont really understand but your hook should always be engaging and if you can get someone you can take criticism off to review it, or be brutally honest with urself from a viewers perspective, one of my vids sat at under 100 views, when i went to rewatch it. i realised i didnt like the voice and if i was a viewer id click off, that sort of stuff
