Well played. For the dynamics, as Justin suggests, if you're pumping 8ths then try to put an accent on beats 2 and 4. Or, try to put an accent on all the downbeats and then just lightly brush the bass strings on the upbeats.
I think of this song as having 3 parts (verse, pre chorus and chorus, and bridge). The chord progression is the same for the first 2 parts and similar for the 3rd. To distinguish them you want each part to have a different feel. You can achieve that with volume, dynamics, and rhythm.
