Thank you for your contribution @elsedongusu. I have some suggestions:
I would like to see more details in the text supporting your video tutorial. Please refer to other approved video tutorials in Utopian as a guide to help you figure out how much text you should use to support your work.
Audio - There is a hissing sound throughout your video. This may be caused by your microphone or your audio recording software. Please do some research on how you can reduce this background noise? There is also some unwanted noises (paper moving, hand noises, room sound, etc.) Be sure to speak closely into your microphone and avoid unwanted noises.
Be sure to explain why you are writing important code functions. Learners need to know why you are making the choices you are making.
Your English is understandable, but there are times when you seem unsure. I advise you to practice speaking your tutorial through before you begin recording.
Consider the complexity of the content of your tutorials. There is room for simpler coding examples in Utopian, but you need to be sure that your work is exceptional educational quality.
