Not a lot you can do about the vocal really. Some delay on the vocal may hide it, but will make the voice sound a little echo heavy. Second break down with the vocal is a little long winded. Drop is sweet. Nice idea. Some of the drums i think are clashing eq wise making it sound a little untidy. Too many highs clashing. Need to use less of the siren sample and vocals, They are good but repeat too much.
Nice work mate. keep it up
