Sounds good!! But yea like most said at some point the vocal disappears. Also before the drop happens you can either have a quarter note of just
"silence" or a short fade in fx. Anything to make the transition sound more smoother. As for the brick wall thing, I personally don't think its a terrible thing. It doesn't sound too squashed. In the end just double check every sound and make sure that whatever you think should be heard, will be heard.
good luck!!
