More silhouettes of high-rise buildings and skyscrapers. In the foreground trees are silhouetted against these tall buildings.
The following images are more like coloured illustrations, made out of photos shot at dusk.
This graphic or illustration is of three skyscraper silhouettes with a tree silhouetted inbetween. Some of the windows in the buildings have lights. A streetlight in the foreground adds interest. The background is blue and green and everything else is black.
The next picture has two silhouetted buildings with a bright street light in the foreground. Quite a few of the windows show light. The background is light blue and the buildings dark brown.
In the picture below the background is blue, but the windows are dark. The effect is of people having gone to sleep. Two streetlights are visible in the photograph. There are also silhouettes of other smaller buildings to the right of the image.
This last illustration is more like a silhouette of a cluster of tall buildings against a blue sky which has been treated with some special effects (photoshop). The silhouette looks almost like a castle as the lines between the buildings are not visible.
