Well, I have not finished the course yet. But I think it's important to anyone see what normal people (i mean, not cg superpower people, like kent and jonatham as well) can do.
As I commented on youtube, I had, I'm having actually, many troubles following this series, many things just don't happen like in the video. It was one point that made me consider to be a citizen.
What I want to make clear is that many troubles that I had were result from a bad retopo and UV unwrap concepts and changes in the sculpt after baking displacements. If you want to make your model awesome like kent's, the secret is don't get the next step before the actual is perfect or quite that.
