One of the things I like about painting scenes like this is that I get to play with colors less frequently used in my pieces of the natural world. I probably used more cadmium lemon in the underpainting of the flag than I have used in 8 months!
Piece by piece, step by step. For me, a painting like this can't be rushed. It is the detail which helps inform the story. Though it might seem tedious from the outside, the chance to work with some different colors to come up with just the right hue keeps me interested, even fascinated, with the process.
