Fun With Blues

The night sky is going to take a lot of layers of transparent blue, mostly Ultramarine or French Ultramarine, to create the kind of depth I'm looking for. Also, there's a faint glow around the areas where the white lights meet the sky. The Radiant Blue from Gamblin and regular, plain old Cobalt, are helping to make that subtle transition. The streakiness will disappear over time.

I'm also brushing a thin layer of the blue over a couple of blackened spots, like the trees and the upright structures, to give those places some extra depth and dimension.
