Oh man.
First off, I definitely agree about the constant chugging throughout the breakdown. If you're THAT set on keeping it in there, maybe change it to an open and slowly bend the note up and then back down.
Secondly, it sounds like the actual rhythm in the breakdown is quite off...is it on time for the key signature/tempo? Because honestly it sounds like you just randomly slipped kicks into random parts to make a breakdown.
Thirdly, the drum fills show that you're not exactly a drummer... They don't sound very realistic if even playable.
Also, the reverse cymbal/cymbal hit in the very beginning sounds out of place. Either take it out or drown it in reverb.
Other than that, I like the tone!
