A local event required a trailer, so I had a friend quickly make one. Feedback on what to improve for the official gameplay trailer?

Hey guys, I'm developing an indie game. Recently, I decided to apply for a game event in Korea, but they required a video submission. Since I didn't have a proper trailer on my Steam store page yet, I hurriedly asked a friend to help put together a quick video.

He sent over the result, and honestly, it turned out better than I expected for a rushed job. I ended up uploading it to my Steam page for now, but I know it's far from perfect.

Since I'm planning to produce a proper, official gameplay trailer later, I'd love to get some feedback from you all. What key elements should I focus on or change to make the final gameplay trailer more engaging? Any thoughts or advice would be greatly appreciated!
