Final Layout:
The biggest light is the "spotlight" illumination in the middle of the picture, an element characteristic of the style I was emulating. Most of the animation in a scene occurs within the spotlight. The source of the "spotlight" is the sun, though it's cut off in a compositional way rather than by surrounding objects. The spotlight reflects onto the bottom parts of the buildings, and gives an under lighting to the overhanging architectural elements.
There are also several windows that are illuminated from within, as well as a semi lit row of light bulbs under the awning of the bar. The window light reflects on the surrounding windowframe, bounces off the sign on the bar, etc. and the light bulbs cast warmth into the shadow under the awning.
Several of the unlit light bulbs reflect the lit light bulbs (speculars).
The focus point is sidewalk in midfield, and the alleyway that leads off of it. The spotlight serves to focus attention there, and the eye is naturally drawn into the alley by the misty blue of growing distance. Most of the detail is focused around the spotlight area; buildings further away from the focal point are more vague.
There isn`t much perspective in this. There is vague 1-point perspective down the alleyway.
There is some rim lightning on the sign, on the unlit light bulbs, and on some of the windowsills.
Hue, value, saturation:
In the style of 101 Dalmatians, I kept to low saturation colours that carefully tread between cold and warm hues.
