Professional Job Recreation

I made an advert 1 year ago for one of my courses, and I sent the raw files on a freelance work website to another person who made the final video.
This time I tried to make the same thing as he did but on my own - only a few seconds - after I understood the method of removing the green screen as well as controlling the colors.
The final video of the freelancer is on this link:
