These are down.
Construction of a basic head,
Anatomy of a human skull videos,
The heavy damage columns,
and the blue alien bust.
everything else seems to be fine, but I would wait a week if you still feel hesitant.
FYI: some of the video have multiple sections broken down in them. Like the master class has 9 videos averaging 15mins each in it covering diferent things. Still worth the price in my opinion.
