This is a really fun jam tracks with a high-energy reggae groove followed by a jazzy bridge with sweet chord changes. Think about not just changing scales and modes between the A and B sections, but your sound. Try a wailing overdriven guitar tone on the A section and then switch to a jazzy clean sound for the bridge. That will also help change your phrasing to match the contrasting sections. Remember to never forget about having awesome tone, whatever it is that you're playing.
