This is a painting of a photo I made in Lawn Hill National Park on the border of Queensland and the Northern Territory last May. We had climbed up a rocky track to a high point looking over the gorge. I only used Ultramarine Blue and Burnt Sienna, learning to paint with a limited palette in Michael Winter's class. Moving the brush a lot enhanced the texture on the trunk.
This is another quite small painting using the same limited palette. The tones were painted on roughly first and the details added later. I walk in these gardens most weeks and take lots of photos to use in paintings. It's amazing how such dark tones can be made without using black which tends to deaden paintings.
