Good job on Time of Your Life. Make sure you are playing it daily for around 20 minutes to strengthen your callouses. Once you’re pretty comfortable with the chords and the shifts, try playing along with the original recording.
Nice work learning Crazy train. Keep working on the alternate picking. Break the riff down into shorter sections and practice those individually before trying the whole song again. minimum 20 minutes per day. Playy with the power chord shape on different fretts as well. minimum 5 minutes a day.
