Choosing the Best Video for Discovery Ads

I could use your help please. ⬇️🙏😊 . . I’m going to attempt some discovery ads to photographers to get them to find me and grab either my posing guide download or come to my free speed posing class... . My three videos are in the carousel. Which would you click on? 1, 2 or 3? (Note they’re cropped bc Instagram but ignore that part :) . . Also, if you don’t have either of those things they’re in my link in bio! . . I’ll probably delete this soon. :) . . @ericalynnnyc shot with the @canonusa m50mkii and ef-m 22mm ISO 800 f/5.6 1/100th . .
