Not bad
Just work on keyframing: make the screen shows more the hits,actually is hard to see the dms
also,the aong selection isnt that good,i will send u songs to sync better later
I mean,use heavy hits songs,theyook better for sync.

tip:
1)slow down a bit before the hit and song beat,then speed up and dm exality on the beat,and make the scene get slower but not-so-slow.

2)right click on the video and search for resample,click on "Disable resample",it will avoid the bad frame morph,ik sometimes motio blur is good,but if you want motion blur,use RSMB instead.
also,without resample you can try to render 60FPS,they look much better(but 30fps looks good too)
