Le Havre with rain clouds

Lightly sketch the main shapes: buildings, boats, and horizon line.

Apply a light wash of diluted grey and purple for the sky, suggesting rain clouds.

Add a base layer of pale yellow and green to the water, leaving some areas white.

Paint the buildings with loose washes of various colors like yellow, pink, blue, and green.

Add darker tones to the boats and figures using brown and black.

Define the edges of the buildings and boats with black ink or a fine-tipped pen.

Add details like flags and windows with watercolor or colored pencils.

Refine the water by adding subtle wave lines with a darker shade of green or blue.
