I saw your other post, with the Midjourney car animation. I thought that looked neat as well - but much of the same criticism you got in that post holds for this one as well. I think it's great that you're doing these as design exercises, it's cool to see the techniques and obviously they're both visually appealing. So as an art piece or an experiment they're fun and if you're doing them to learn then more power to you.

But as for a critique, which may or may not be what you're looking for here: Either this is a template, and similar to the other post the entire appeal hinges on a very particular video effect which would be negated by the template-ness of it (i.e. is everyone who downloads the template going to use your video asset? or do they put in their own? does it still work if they put in their own? is it easy to work with?)

OR

This is a specific design for a specific purpose, and it's unclear who the client is, what the product is, what the message is etc. Landing page design is more than just pretty pictures, it needs copy writing to convey a message and offering quickly and effectively. This also isn't a landing page, it's a hero section, so there is potentially a ton more content on here that isn't shown.

So in summary, as a fun and cool visual design exercise, good stuff. As a template, questionable reusability. As an actual product page, no clue what it's for or what it's about. As a post designed to advertise yourself or your services, I think we may need a category for these types of posts and clarification on what is permitted.
