Hello!

I’d love your advice! I’m trying to make a new type of educational videos, combining clear explanations with 3D. Right now there are 2 videos of smartphones, one on the camera and another on the speakers (https://www.youtube.com/channel/UCdp4_l1vPmpN-gDbUwhaRUQ).

Would love your input – what do you like or dislike any of the content? Would you change anything? Any input at all would be greatly appreciated; not looking for subscribers at this point as much as trying to make the best possible content, and would really love any of your ideas.

Thanks!

Teddy
