Here is my progress for the Psychedelic poster. I chose the truism- You are guileless in your dreams. This evoked imagery of naivety and carefreeness in my mind. Eventually, this lead my thoughts to 'The Wizard of Oz' - often considered a psychedelic story, and so I chose to base my poster on themes from 'Thw Wizard of Oz'.
There are several things to improve. For one, I intend to change the typography a little, so the letters fit into one another a little better. Also, I'm thinking of turning the yellow hair into the yellow brick road instead. So far, I think the poster is somewhat plain.
