a row of skyscrapers
thick clouds in the sky
this is in a city
the photo is in grayscale
The sky is gray
The sky is cloudy
The sky is threatening
The sky is gloomy
The sky is sinister
The sky is overcast
The sky is unfavorable
The sky is ominous
The water is calm
The water is ripply
body of water
a city's skyline
black and white photo of city skyline of buildings, tall buildings along river and a bridge over it with a boat sailing past in the middle
