I think the colours are absolutely beautiful, really good work on that. One thing I'd like to point out on is the camera, which I think is a bit too static, I'd like to see some more motion (don't be batshit crazy with it, just some subtle rotation around the Tori would be great). I think there needs to be more emphasis on the sync. I can see sync, but it's difficult to notice unless you try to notice it.
Also try to make the start and end a bit more smooth.
