VFX Compositing - After Effects

here's my VFX comp scene which i created in After Effects using some VFX elements like from ActionVFX.
i have already uploaded this post on insta almost 1 month ago, i'm posting lately on ArtStation.
i have also added the actual scene of Before/After.

yes there are lots of things to get improved, for that reason i would like to get feedback in comments please :)
please let me know how can i improve it more, what lacks.
Thank you.
