Thanks for stopping by and leaving such a valuable comment. As I've always said, each painting to date has been a matter of experimentation. In each one, I've tried something; in this case, I was testing three new brushes and how they flow through their shape. I found I could do some things faster with them.
Then I focused more on that than on other details of the painting. But the experience was worth it, and another aspect is that the final colors diminish significantly when the acrylic dries; it could be the mark. And some of the transparencies I tried, how they look with different shades.
It's time to keep studying and experimenting.
