Honestly, I find that inorganic, mechanical things are far easier to design in Blender, but humans, or anything living, is much more difficult. While I understand that lots of people are looking for more functionality things in their courses, I also think that this aspect is something that’s overlooked.
I understand that the Blender course does go into modeling a human head, and while I haven’t reached that point yet, I also understand that there’s much more to modeling a whole human. Especially clothing.
While I don’t ACTUALLY know what would be an appropriate “flow” for the course, I think it could go something like this:
Low-poly/“blocky” human > Clothing/Armor/Hair > Rigging/Animating the human > Non-human (cat?)
Of course, I would obviously prefer it in the order of whatever the course designers thought would be best.
