step2 & 3 "mechanical pencil" were just perfect, also playing with some elliptical forms which are not drawn but the observer's eye is lead to complete them. Sometimes rubbering don't take us to the good point, so, I definitively forced my self to use it at less as possible. It interrupts the flow, the Tao, the Chi, the rhythm. I rather prefer your "fresh&flow" artwork.
Eraser does affect the mind ! Very odd, but very true !
