I think it doesn't look bad, but it doesn't look professional. Most of the images are pixellated and the transitions are not so smooth. I think the best way of making the promo video, is by using vector images and go for a cartooney art style. One trailer I really like is the Dogecoin one for example: https://www.youtube.com/watch?v=000al7ru3ms   It's quick, fun and gets the message through. It represents everything Doge stands for.
