Thank you! I added the following in my description box. Thanks to you, a lot of people, I hope will discover and join Krita’s forum. Also, they will enjoy new themes.
PS. In the video, at minute 2:36 I say TOOLBAR rather than TOOLBOX. Thank you, Ahabgreybeard from Krita’s forum, for catching my mistake. 
UPDATE: FROM AHABGREYBEARD _ KRITA’S FORUM.
Our good friend Ahabgreybeard wanted to share with you two links. These links will help you get more themes, he said:
https://krita-artists.org/tag/themes
He added, I quote: “Not all topics that provide themes for download have a ‘themes’ tag so a general search for “theme” is a good idea. Also, there are topics that describe how to install themes (easy) and how to edit existing themes to change colors (tricky but not difficult).”
So, THANK YOU Ahab for your help! I really appreciate you and I am sure the viewers of this little channel will too.
