I use the words that I am able to use at the moment and I also have a language problem. anyway, I found the original and it's not private so I'm posting the whole photo. I add one thing, I remember seeing two photos with different subjects whose result was similar to that obtained in this photo and the watercolor effect as regards the jagged shape and the splashes was identical (although obviously the effect watercolor modified the different objects portrayed, and did not overlap by deleting them), so my hypothesis was that to obtain the effects of the two photos he had not used brushes but a texture.
