This is really pleasant to watch! I normally really dislike cross dissolves because they distract me and make me overly conscious of the camera, but the shot choices that you choose are so solid and strong that I think it's really good!
With that said I'd still like to see this edit without any cross dissolves, just as a reference.
I think you found the best camera angles to use for this song. There is one shot of Sia from the side of the stage and we can see the audience, I think from Joe's camera, that you should add to your cut. If there is ever an opportunity to show the audience from the stage DO IT!
