Based on my experience I know that an important aspect of any feature that begins to add a bit of added stress in a ride is the entrance and exit associated with the feature.
If the entrance to the feature seems difficult, then looking forward to taking on a harder feature becomes a bit of a negative. And likewise regarding the exit... If it seems to have some difficulty related to it, the feature that comes before becomes a bit of a negative.
For beginner level riders there is a need to instill/encourage confidence in their ability to accomplish what they're going to try and do. Not everyone is like that, as some folks are just born with bigger 'uns than others. But on average, folks need to feel good about what they are attempting, before attempting it for the first time. So although it sounds like you did exactly what needed to be done on the feature itself... You didn't speak much on the entrance and exit to it, which is why I'm bringing it up.
Skill development is all about building confidence to then train on proper technique/application. And it's one of the things I like about Brushy Creek... It pretty much has trails that allow development progress to take place. The first time I took my wife riding there we did the easier part to begin with (the trails that are out by the lake). When we came back to the parking lot by the skateboard area she asked "What else"... And so I took her up what I think is Deception (not sure of the names), and she was stoked to do it, because her confidence level was high from riding the other section well. She had to walk a few parts of Deception, but she was good with that given her being able to ride maybe 70% of it (what I took her on).
