Hi @Dr. Martin Karnolsky, thanks for sharing your video! I'm bumping your post so other instructors can help you by providing feedback. Have you already shared it with the Udemy team?
I am not a Udemy staff i am an instructor as well so this is just my opinion 😉
* Sound is clear, great!
* Lighting seems good
* Background can be improved, maybe not too complicated with different objects but this seems a little bit random for me. Maybe with a couple of objects that may relate to the course content to give it a classy look.
* Content: Since i am a software developer i am pretty far from the subject but it looks good 🙂
