RE: Moleskine in my pocket (and ballpoint pen as well)

Your drawings are great. I too was amazed when I found out for the first time how good is a ball-point pen for drawing. Especially when your strokes are small and jittery like mine. most of my drawings from elementary school were done with it.
One way to use it is to build up your color spot (like layering, but not quite, without lifting the pen). That way it feels like drawing with an HB pencil
