let me tell you "hundreds of thousands of thanks holy lord" to be honest wonderful stroke art. 
 I have seen channels from other artists besides yours (something else before continuing, I did not even have an idea of your channel, sorry for the xD data ), but I do not see the videos completely or skipped part of the video or live broadcast , since I lack patience, but this time I made an effort; I see that if you have a lot of patience (a 4-hour video is BRUTAL ), according to me, my line drawings (they are only doodles) are just meaningless fragments.
 Greetings and I wish you good health and your family, for the problem that affects us all (the famous COVID19) have a good day 

happy Birthday my friend 
I wish you a very happy and pleasant day 
greetings and hugs 
forgive for the delay of the congratulation 

Happy Birthday, may your wishes come true
