After the two-month research, I give an overview of the work by elaborating a collection of the brushes created.
It's still too early to understand the scope of the research... but I wanted to give a general picture and thus identify possible convergences between the different types of brushes that I created for Gimp, in fact, some of them will have to be reviewed and reworked for the series of chinese brushes (sumi-e).
