Start with Themes
Don't know what to create? Start with a theme. Themes are big ideas that can spark new ideas. Create a mind map with your theme in the middle and go crazy brainstorming different topics, ideas, images, etc.... related to that theme.
Theme Ideas
identity
time
propaganda
complaints
doors/portals
dreams/surrealism
now vs. then
words/letters/text
fantasy
creatures
geology
costumes
Here is an awesome example of what a mind map could look like.
REMINDER: This is ONE personal perspective of this theme, everyone's mind map should look different.
