The script was well written, and the characters were distinct. The social worker seemed pompous.
I'm going to build on what LuckyDee mentioned. It sounds like you were adjusting off the raw microphone input. With low power microphones, it helps to Normalize the audio track (in Audacity, under the Effect tab), which raises the volume of the selection.
The double edge of normalizing is that it boosts everything, so it increases the ambient background noise as well. If your computer is anything like mine and sounds like an entire air force breaking the sound barrier, that can be a challenge. More on that in the VO Home Studio link on the VAC rules post if you're interested.
Nice to see you submit again after a four year break, I hope you stick around :)
