To paint a sunset painting with clouds, you can follow these steps^{1 2}:

1. Use X shape brush strokes with a Filbert or flat brush to create a messy blend of bright blue and white paint across the top of the canvas.
2. Add overlapping layers of varying colors.
3. Create an organic composition.
4. Overlap layers with feathery brushstrokes.
5. Blend the edges of the water with a lightly wet brush.
6. Add clouds using cool red, making sure they look like fluffy blobs.
7. Add dark spots with a purple mixture on the clouds, focusing on the bottoms and middle.
