A funny exercise for your right hand, pickstrokes are notated. I suggest to hold the fingers of your left hand on the frets (like if you're playing a chord and sweeping down with your right hand) for the first Dm arpeggio (misure 1) and the first two arpeggios of the B section (Dm - Eb°). In this way you can play the passages more easily and with a clean sound.
Sorry for some missing pickstrokes notations (a couple, not more) but PowerTab have a well-known bug and sometimes it doesn't seems to work good with this feature.
Good practice and remember to use the metronome.
