(1. The tags seem lazily placed on sections without a transition. They are also very loud, compared to the rest of the song. I would take a look at your levels.
(2. The 808 is tuned incorrectly, it doesn't flow well because the kick is overpowering. Whenever it hits, it damages the mix, and that's what you do not want. However, I would advise you to EQ the unwanted frequencies. It doesn't need to sound really punchy, but 'just right', in my opinion.
