I agree, it needs more variation and a bit more structure, you don't really work up to a drop it just kinda happens - I'd use some risers and some extra drums to get there. Also think your drums are kinda quiet, even for liquid. Hope that helps!
I think you should get more attantion to post production. I think you should give more attention to post production. Try to change volume of kick and snare. You can make for example two audio tracks with same instrument and set pan -50L, -50R and add delay on left 0.03 it's make it more air.
