Okay. I had taken a day to let the line sketch sit. Today I came back to it and was able to look at it afresh. I adjusted the lines and angles create more a more fluid visual flow and had just started shading in the values. Then I set it down to retire to bed, and the damn cat spills a glass of water on the whole damn thing.
What was I thinking, leaving a glass of water next to my work??? oh well, its salvageble! The paper is utterly ruined, though.
