Great video. I loved it. I'm sure that in a longer one you could provide more tech details to those who are just learning how to use water colors or gouache.
I think it is a great excercise to copy masters' works. I had a lit professor who suggested re-writing entirely pieces from favorite writers so that we could grasp a word-by-word feeling of what it took to write the whole text.
I think you did a fanstastic job making watercolors look like oil.
It looks really amazing
