You're welcome.
What exactly do you mean by cleanliness of image? Using BH's profiles as a reference is a good idea of course (a very good one even - I've reverse-engineered his material to develop new techniques but he can't prove it so I'm lawsuit-safe
) but all of the other members posting here have drawings that should also be carefully studied. IMHO there is no limit in what one can learn from others, just by studying like that.
