This could be a great song, IMHO I think it would benefit greatly from re-structuring, The last part sounds like a chorus to me, and the 3rd section is a bridge, if you changed the order to
verse 1,
chorus,
verse 2,
chorus,
bridge,
chorus
it would make the song drive along a lot better, the last section is great and would make a great hook.
Just my thoughts, check out the tracks on my youtube link below and take note of the structure, Mikey
