The vibrant yellow-green foliage, the bright white sunlight in the sky, the deep shadows, and the vibrant reddish brown of the redwood bark all work together to give this painting a warm and sunny feeling.
The hot summer sun casts light on the rough tree bark.
Looking at the whole image, we get the feeling of standing in the forest surrounded by this circle of giant trees.
A closer look at the details shows individual brush strokes, placed expressively in swipes and dots that form the negative shapes of light coming through the tree canopy, or branches full of greenery.
