I really appreciate the challenge you presented in your response, Tuomas. One of the most amazing things about art is that it is so intertwined with other fields such as science, math, history, and language. A single piece of art can have so many different meanings given the context of an article, book, series, location, document, or stand-alone piece. My own art experience has centered around free-hand drawing, historical painting, and scientific illustration, so I had not been initially inclined towards your reading.
From a more journalistic approach I can see how critical the Matisse inspiration is. Perhaps your work speaks more to what has or has not changed in the passage of 100 years, in Morocco but also the world at large. I admire that you followed Matisse's journey. When I think of art as a portal for social activism, I consider graffiti, pamphlets, performance, films, and of course photo journalism. I also think that it is valuable to view art in multiple contexts because such important messages are more able to reach a wider audience.
In capturing an unsuccessful moment, I believe that you do capture the appearance and a glimpse of the truth when you dig deeper, like you said. However, I wonder what your criteria is then for a photograph to become part of your publicly viewed series because you don't include every unsuccessful moment.
