No, some start loose. I believe that the process is that they keep homing in on the subject until they reach their goal. I have worked with some who do their drawings with nothing but straight lines and achieve the roundness by cutting away at the corners until they get the likeness they are seeking. There are an infinite number of ways to get there. How many times have you heard, "The pleasure is not getting there but the journey?" Keep homing in on your drawing and values. Once that you are satisfied with your results, then attack the problem of color. As I understand it, this is a method used by many. As for me, I'm too stubborn. I like the torture of working alla prima. I think that it is the masochist in me!
