I like how deep your voice is, it has a bit of a rough feel to it that fits the role well. One little nitpick might be that when you do multiple line deliveries, you tend to say the line in the same way, just making certain words louder. Maybe next time, you could try giving off more of a slightly different emotion with each delivery - tired, angry, dismissive, boastful, etc. But otherwise, you've done a great job!
