I mean that the way you switched between the red, blue and green colors did not look good. There was no definition to it. It felt random. I think a better approach would have been to highlight specific objects, mask those out, and then apply your colors to fit with your RGB theme. Rather than just selecting those specific color channels to show wherever they are in the scene.
I don't want to come across mean or overly critical though. I think overall your video is fine.
NOTE: I had confused you with the person who had won akross this year, so I was being a bit more picky expecting more. That was my confusion hahaha.
