You probably came to the wrong place for any realistic or objective assessment.
I thought it was a pretty good work in progress. I agree with the build up/training part making the rest look much more relevant. Good song choice and aside from the throws being just a hair off from the music (which you already addressed) I don't see much to improve on. Good job so far. My only suggestion would be to put the Miesha 2 stuff at the end after whatever other highlights you plan on adding. I like when these things go chronologically. Seems to tell the story more for me. Just my opinion though.
As it is now (ignoring the length for a WIP) 8.5/10
The training scenes on the beach went on way too long. That whole montage should be 15 _ 20 seconds max. Don't worry about trying to fit that beach stuff with the song. Use slow mo of her throwing people if that is what you trying to do (going to music)
