Built my first landing page - looking for feedback on structure

After a few ups and downs, I have created my first landing page.

I created it for a company that is currently missing a website. It would be used similarly to a portfolio website with some images of their previous endeavours and a prompt to apply.

The hero image is supposed to be a promo video, but I’ve put an image there for now as I don’t have access to the video yet.

I am unsure if I have implemented everything in an effective manner. Would love to know if there’s room for improvement in the structure of the site.

Actually, as I was gonna take a screenshot of the website for a preview in this post, I tried to zoom out in the browser to try to capture a large snapshot of the website in one go. I noticed the images didn’t scale down. Is it because I’ve used % widths/heights? What would be a better option?
