I watched a couple of the videos from the series this morning.
Video 1 Creating a Melody and Video 10 Creating an intro.

My initial reactions
Eli moves quickly through the material. Pay attention.
He teaches with both BIAB and his DAW (Logic). If you use Logic you will likely pick up some extra info from this.

The project is what you would expect from Eli Krantzberg. Professionally done and comprehensive. Good work

Admittedly I watched about 10% of the material.
Someone else may do a more exhaustive review. Truth is, these features are not part of BIAB that I use (at least not yet). I may use the Intro feature in the future.
Likely I'll watch all of them and see what Logic tricks I come up with.
