I love this.  Your acting is excellent and your audio quality is great.  Let me just get it out of the way that I think you are the best so far, but do you think you can submit another audition that's just the part at the end where you're yelling and put a bit more oomf into it?  You don't necessarily need to be actually yelling but I noticed you kind of started to whisper almost, which I used to do too.  Confidence is key when doing parts that require fight sound effects and shouting.  sometimes it helps if you kind of actually imagine yourself pushing or punching or something that might make you shout or grunt.  When i do it sometimes i even swing my arms around.  I still think you're the best so far and am considering you for the role.  Don't be afraid to let loose and blast my eardrums off lol.
