Learned a couple things with this drawing. One, watch proportions! The head shape and eye size is a little different than the reference. It’s fine for practice, but not entirely *right*. Second, never use paint to do what you should have done with ink. I tried to get lazy and beef up one of the black neck stripes with Sodalite, and it just looked weird. Better to have just scratched away at it a little longer.
Third, perhaps, plan ahead. I was going to draw the entire bird and could see after a while that maybe 60% of him would fit on the page by the time I got done. Oops. Head portrait it is! This was about all I had time to draw anyway. Might do a full-bird drawing and stretch it over two days.
