So, continuing with the idea of ambush drawing.
My personal goal for this meeting would be to see, if I can grasp the difference between working with sangina, coal and regular pencil.
For me the feeling of all three materials is vastly different and recently it is becoming clear, that each of them demands specific technique, as well as being best suited for very particular content of the picture.
So I'll see what I can deduce from making sketches in these three types of media and comparing them. Should be fun :)
