I'm trying to set up a base layer that will help me when I am working on smaller details in the final stages. I want each large area to already have a defined value range, so I don't make the darks too dark and or the lights too light within a given area.
I'm also avoiding painting the lightest lights or darkest darks at this point because I want to reserve the option to punch a dark back,or pop a light out from this range of midtones.
Once this layer is dry I think I'm ready to move on to the fun part, the actual painting.
