Thank you so much for sharing the video and pictures with us!
I have couple of suggestions about the videos: if you will record them with the a phone/iPad placed horizontally, you will receive the full screen.
There is a free video edior that you can use is Windows Movie Maker. It is free.

About Ramen's progress. He is doing great! I hav couple of suggestions.
1. Are you following customised Curriculum for his age?
2. Ask him to master the pieces that he had learned with TEACHING VIDEOS:
softmozart.com/forum/55-teaching-videos/...roductory-songs.html
Here is the example how to do it:
First he supposed to play with the video that has metronome in it. After mastering it, he has to play it artistically with a pianist.
Please, accomplish this goal and I will write the repertoir that I would recommend for him to play next,
