Overall strumming was even. Kudos.
Singing was pretty much in scale. g00d.
@0:13 - you should have used pull offs and hammer ons instead of picking each n every note.
Singing - need to get strength in vocals. Easy pitches (the ones normally encountered while talking) were having good loudness, however, whenver there was a change in pitch to higher or lower than normal, the vocals lost power.
