I think that teaching how to model such a detailed orc this early in the course is a bit too big of a jump from the robot in Mech Master. What with all the details to keep in mind, I’ve felt a bit overwhelmed. Doing very badly at the challenges didn’t do my morale any favors.
As for how things can be improved, perhaps it’d be better to teach modeling a more stylized orc before going for one so detailed. In my opinion, the reduction in complexity would make things more manageable. The challenge difficulty could be more in line with those of courses like the Complete Unity 3D Developer one.
