Very well structured course! Love the fact that the speech is slow and clear ( and English accent ). That course cannot be compared to any other which you can find for free or in youtube.
I think it's a good idea to make the drawing in pdf file to download, so when you start your wireframe you can actually be guided by the drawing rather than the video.
I struggled with some wireframe geometry, so may be a good option if exercises training/tutorial is accessible at any time of the course, rather than being last.
I wish to see another tutorial based on recognizing feature, where different features of 3D object are shown and different methods of approaching discussed (area mill, dynamic mill, peel mill, blend mill, etc).
Great work! Amazing Essential training! Amazing basis to build on!
