Here's an update after some progress made.
Since last posting of an image ran into an obstacle. The size of the digital painting was accumulating too much memory, reached a level of 294mb at a size of 5700 X 6618, 300 dpi. The reason I stress too much memory is that the program was beginning to run very slowly and occasionally freeze. To alleviate the situation the image was reduced to 2842px X 3300px and 96 dpi, with an end result of a 82mb size file. If I had continued with the original size the problems of slowing and freezing would get worse. The larger size is better for exploding views to high levels for close attention and work on details. Still a long way to go.
