Drawbridge in St. Petersburg. Russia coloring page

Cityscape with drawbridge spanning a river, adorned with lanterns and clouds in the sky.
On the coloring page, there is a large concrete drawbridge stretching across a wide murky river. The massive structure looks imposing amidst the cityscape of tall buildings and bridges on either side. The bridge is cast in a monochrome gray and has large metal lanterns placed symmetrically on either side. The sky is an ominous grey and filled with dark clouds, adding a touch of mystery to the scene. To colour the image, I would suggest shades of gray, blues and neutral tones to enhance the peaceful yet mysterious atmosphere of the page. The river could be a dark navy blue, while the buildings could be painted with light gray and white. For a inventive look, the metal lanterns could be painted in silver, and different shades of grey could be used to bring out the details of the stone work on the bridge.
