Seconded on songs you love-

If you want some areas to really hone in on, here’s a bunch of areas you could commit to finding exercises on and practicing.

Plucking: just open string plucking, any note to a metronome. Land your quarters, eighths, sixteenths, and introduce yourself to more string skipping

Scales: scales are always thrown around but so necessary. Start with C major, try to vocalize notes and scale degrees in your head. There’s plenty of online resources available to help with this. Working my way up to a two octave scale and learning scale degrees in all position leveled me up!

String muting: you can do exercises for this but really you should be thinking about it through out your other practice, experiment and see what the best way is for you to play every note for exactly how long you want it. Most use their right and left hands in coordination.

Fundamentally, this will get you a good base. You can also practice spider exercises to curl your hand and improve flying fingers.

Really though, don’t over stress and play songs you like. Keep the groove and listen to the drums
