Good afternoon, the explanations are on point and everything was perfect. Although I want to call out that the voice was a bit quiet and soft. I recommend to have the voice much more clearer and louder. Adding to that after you explained or read the descriptions simplify it to simple terms so that it would be much simpler to understand, and it would be much better if you translate it to Tagalog so that local Filipino's would understand this topic much more. That's all and don't interpret this comment to the negative way.
