Manhattan Skyline at Dusk

The Manhattan skyline rises across the river at dusk as lights begin to glow under a purple sky.

The skyline has a strong lower edge, but its windows and rooftop shapes make many small groups above it. Build the river reflection separately from the buildings, then use the tallest silhouettes to orient the purple sky. Lights coming on give the darker facades small warm landmarks instead of one flat city block. Once manhattan skyline at dusk is taking shape, the less varied pieces around it become easier to judge by edge and tone.
