Some online inspiration comes from :
Assignment details: Design and illustrate a cityscape using the perspective tool and a unique color scheme. Your cityscape can be fantasy, based on a real place, or a combination of the two. Build a unique world and put as many details in as possible, continuing to build our storytelling skills.
Your landscape/cityscape can be anywhere in the world… Where do you want to go??
I liked this one for its use of an antique map for reference. Remember my post on digital library collections that are now all available via public domain.
Be inspired! Excellent student examples from previous Illustrator 2 classes!
