I hope, you don't mind some criticism?
When I try to watch videos from your channel, stage direction of these videos really disturbs me. 
It becomes especially hard to understand whats going on, when the teacher (you?) shows papers with pictures to the camera, holding them in their hands. These papers are moving, waving, and camera is constantly refocusing. Maybe try to not hold them in hands, but put on the table, like they (you?) do with the paper with the sketch, which is drawn in real-time? Also there are too much surplus explanations in these videos, for my taste. Maybe it'd be better to think over your speech in advance and make it more laconic and informative?
Nevertheless, particular way of drawing "birds-eye" (I didn't know that this foreshortening is called so 
), shown here, made me curious, and probably I'll try it in my comics in the future. People say that it will look more interesting and volumetric, if I will add more different angles, so why not to give it a try?
