Uzaki flashing animation! (need your feedback) (Pixiv Fanbox)

Hey! so i made an uzaki-chan animation. What i want you to help me with is this the beginning. I will expand the shot so it is not a iphone size and you can see the animation better, but what do you think about the beginning? (uzaki checking if there is people around) should i keep it? change it? or go straight to the flashing instead, deleting that part? I'll also add some characters in the distance so let me know wether you want it to be NTR (adding shinichi looking at the beach along with other characters) or ambiguous (leaving shinichi out of that group so you don't know if he is the one recording)
