Retro Space City

Working on branding material and wraps for a cool new project. Started from scratch with the direction and style and we're pretty excited. We're trying to really nail the comic book look of the 50's & 60's. Looking for a little advice, aside from vomiting on the noise and scratchy textures. Stylistically, I think i nailed the astronaut. Just looking for how to translate that to the city. The final product will have some color, just not sure what yet. Check the attachment!
