Hi Chuck,
It is interesting to see how you focus on the objective you set for each of your learning process.
Personally, I find that one can learn different skills, techniques at various stages in one painting, even if you do have a certain objective in mind. For example, at the planning stage I would focus on massing values, colour co-ordination, and composition as a whole. At the execution stage, I would still keep my objectivity in mind, but also focus on my texture and brush strokes, colours etc. And at the final stage, I would try and see where I can proofread my painting, manipulate edges, brushstrokes. This is by all mean, a discussion, and I am not in anyway criticising your way of experimenting your work.
I look forward to seeing more of your work.
Mai
