It is a good effort but it all depends on the audience you want to reach out to...
Here my suggestions:
- If it is a worldbuilding exercise for a story, it would be better to use a slide show or a bible with high quality images (you have some of them in the video) and use transitions for animations, with minimalistic focused backgrounds, if you want to have a video at all costs.
- Change the voice. There are plenty of free AI natural voices (e.g. you can access them through Pinokio, and depending on your hardware, it will be fast enough to create several waves files). You might need a calm, warm voice or a fast pacing one depending on the effect you want to have.
- Too many details, it is difficult to follow.
- Build this tour as a story, don't just list the items, create an engaging story that run like a carousel through the elements of your world.
