Hello Ilia
I love your cartoon. To me it seems more like a acomplete one color painting which stands for itself. My way of work is different however. I use to draw general plan of the figures and events without going into details to much. I also never trace my cartoons on the mortar but rather copy them freely by eyes. I also like to improvise during the work and do not hasitate to erase (removing acomplete giornata, intonaco and all..) when needed. It demands a very careful handling, on one hand, but enable (me) more freedom in attitude and performance. This example is adetail from a commissioned fresco that was performed that way.
