This is a plein air (mostly...) that I just finished. The weather was cold on Friday morning, but forecast to warm quickly, so I got gear together and went out to the Parklands at about noon. It was a great day to be out, though windy.
I used a limited palette: Ivory black, titanium white, burnt sienna, yellow ochre, burnt umber, and cerulean blue.
I finished most of this on-site, but did a little fine-tuning and touching up when I got home.
