I think that it may have to do with the rain sound effects.
I think the “audiojungle” voice is too repetitive and loud. jus kidding thats not the point, but also its pretty repetitive, don’t use it so tightly. I think the mix has problems, pretty muddy, lots of low mids and no highs, it pretty dull, also the ending is not something you expect, its pretty sudden, and the samples are not so realistic. Also not so commercial use of this rather than specific music for a specific movie. Good luck in future
