DeDear, while I have been a teacher in the past (now retired) I am, like you, a student in this class. Keep mixing!
Today I spent 4.5 hours in recording studio, and it is fun to see how quickly and effortlessly the engineer gets things to work. It is all the stuff we have been seeing in Loudon's videos, and more, but applied by a fellow with incredibly good ears to hear what needs fixing.
Cheers
