I see improvement but
1) You really need to work on your freecam. Try to keep the action at a suitable distance instead of zooming in/out so often and try not to end your freecam before your replay ends
2) Disable resampling, it makes it difficult to see what's going on especially with the speed. Consider getting RSMB which is an alternative motion blur program which will make it look far smoother, but increase your render times by a lot (I suggest rendering at 30fps)
Resampling does this
3) Experiment with transitions between clips, this will give your video much more flow
