If you split this painting in half either vertical or horizontal then you will get the same on both sides. That is what makes it a symmetric balanced painting.
One the left hand side there is a pointed mountain type thing that draws attention to that side. On the right hand side there is the sun that draws attention to the right hand side.
This painting is where the orange from the fall leaves blend in with the yellow leaves which blends into the brown mountains and has some blue in the mountains. That blue on the mountains makes the blue sky blend in all together.
In reality the flowers would be larger than the glass that these are in. With a glass this size in the painting and the flowers that size in the painting, it all becomes balanced out.
