Cello - 7

I'm finding working on two pictures difficult..when 'm working on this one, I'm thinking of the other one and vice verse.Still, I've arrived at a sort of compromise...I work on the colour picture during the day light hours, and this one at night. I've had problems with Cello Girl's left hand, which was originally positioned over the neck of the cello, but my drawing was not good and this meant that once dotted it looked clumsy and out of place...so for all those who ask "What happens if you make a mistake?"...this is what I do...I get my rubber (eraser) and remove the ink..you can see the scuffed paper where I did this..so I'm working on some sketches of hands to get it right..I may position the hand higher or lower on the neck and cover the scuffed area in background.
