@wesburke Hi Wes 😊 my suggestion is about the sort of exercises CG Cookie provides. I would suggest to stimulate more doing your own projects for exercises, use the skill learned and actually create something unique. Maybe not for the beginner series, but for some of the intermediate courses and definitely for the advanced courses.
For example;
Johanthan Lampel did this awesome sci-fi environment course. It is training you to be able to create any game asset you want. He is modeling an animated door. What is the exercise? An animated door. Which mean you could follow along with the course, copy everything Lampel is doing, submit that, and get a pass. Not very challenging imo..
Why not ‘create your own sci-fi environment asset, with a movable part, but it can’t be a door’.
That way you are stimulated to actually use the skills and your own imagination, to create something unique. I think this is something you could definitely ask of an advanced blender head.
