African Grey Parrot - WIP

I am painting this boy using that complimentary color scheme again.  That makes the painting "sing" as Arlene Steinberg says and I have to agree with her.  It does take some work and a few layers before the colors start looking like "grey".  Since this image is a 9 x 12, it's going to take some time to get it done.
