I really thought you would show us how to model a chain and a part of the wheel too. That's at least what I thought when I saw pictures on the front page of this course. Picture shows a half modeled wheel, then I thought 'oh great he will show us how to do it''. But nope :) I had to go to YouTube and watch some tutorials, that's not what I want keeping in mind that I'm paying for this.
It is a beginner level course and some of us only started off with Blender days ago. But anyways, you explain everything very well and you have great way to approach our ''beginner brain'' :D!
Just keep in mind that some of us are real noobies.
Thank you!
