The same phrase can sound very different depending on how you play it. Notice how the A section at the end is played legato by using hammers and pulls, while the first A section is all picked notes. Try to keep the volume of your slurs(hammers and pulls) equal to your picked notes. The B section is often complete improv. That's where all the substitution licks are in this arrangement. That way you can get a bunch of ideas on how to play it. It's a great opportunity to use the shuffle button to scramble the licks into new and interesting combinations.
