I thank you very much. I'll tell you that as an artist I'm extremely slow, because I do it in the snippets of time. Something comes out now but will be appreciated in a year, something will not be appreciated at all.
What I can tell you is that if I do a theme it is because it is a source of remembrance of a place, of a person, of a trip, of something I use and therefore of my experience. I am happy that my work is appreciated, I am advantaged by the fact that I have been using Firefox since 2000 !!!
