Character Design Lesson Environment

Today I tried to draw an idea for my spy's environment, but i know what needs to be done to go forward with this idea now.. 

I'm going to do a short storyboard where the setting is on a roof this is so the city isn't to to cluttered and more simplistic and can focus on the spy scenario of unleashing the gadget e. G chasing down a villain. The style needs to be match my character Design and needs to match the surroundings e. G shapes and bold. Shadows Saul bass, spirals and Andy warhol, a bright 60s colour for my spy to stand out and show the personality e. G red.
