That course is JAM PACKED, i went through it one time, and i am certain i am going to repeat it because there are a lot of tips and tricks. I could usually predict the next movements when doing the other courses, but this one had a lot of addendums that forces you to slow down and really learn how deep the texture engine runs. I appreciate that he goes through unwrapping on several passes because that is the core skill, i feel, he really drove home well. I found myself screen shotting the more complicated node trees so i could diagnose them at a future time, because its like one of those dance mats with feet and numbers, only there are like 100 steps and rotations haha.
