plosives even though I'm using a pop screen...

Hi,

My audition to join was rejected, because of low volume and plosives... But the feedback doesn't make total sense to me... I think the recording is pretty clear, and I use a professional pop screen. Can someone listen and let me know what I'm missing? Also, just in terms of gear, I use an audio-technica AT2020, mic stand with stabilization, a pop screen and I record inside of a tiny fabric lined closet. I export from audition.

Any help is appreciated

also, not sure how to attach my file here.
