ways to improve manaflow animation ?

I got this manaflow animation but unlike the last manaflow animation I posted this have sound that T made using my phone to record a video of an object splashing in the water in my bathroom sink. Then I transferred the video to my phone to my computer. Then I added the video in the video sequence editor in blender to delete the video but not the audio Then I pressed renter audio. Then I did some audio editing in audacity to remove background noise and to make the audio louder. then I added the edited audio file into blender video sequence editor . Then I used that same video that I got the audio from as reference to animated the scene in blender. Then I used the video format ffmpeg video to render the animation and audio together. What else can I improve on ?. Please tell me here's my blend file.https://pasteall.org/blend/ad898f57480146818a43f42298be8b66 and the video the I recorded to get the sound from and the rendered animation https://drive.google.com/drive/folders/1Rg0jEfc_M5eoIXz4_MfZwpO5ucbUgi6e?usp=sharing
