Interested in course also..
I know this guy knows what he's doing. But all of the courses Holly puts out (either herself or with others) are a complete trainwreck. There's very little actual explanation or instruction and you're not already fairly familiar with what they're doing, you're going to be lost.
I've seen multiple courses from Holly (got them all here) recently, and they're all such a mess, they're all but unusable.
