Starting with just black and white is really helping to decide what is important and what is superfluous in the initial sketch. The critical thing for me has been using a solid blockish brush and painting in and erasing out until the light shapes are fresh looking and nicely arranged. The balance of the composition is much easier to assess right at the beginning when working this way. 2.5 hours in the field, 1 hour at home adding details and color correcting.
