Chapter 11 is PL OK !
Only a few minor notes for Chapter 12:
The beginning silence is a bit long
3:34 - heard 'bruild' instead of 'build' (very minor, only mentioning it because there are other notes, you can choose if you want to fix it )
Chapter 11 is PL OK !
Chapter 12 is PL OK. I liked your new word. It reminds me of the differences between 'boil' and 'broil', maybe 'bruild' can have some special meaning.
