I was attracted to this because of the color and the layout of "Imagine." I was further impressed with the main text being woven into the word, and even more so by the imagry of the words. With the last section of words, I was just like "wow." Very good job, it's simple, powerful, and effective.
I really like this poster. Nice typography and colors. What I like the most is how you separated IMAGINE into syllables: IM-AG-IN-E ... This breakdown suggests the following: I'M IN AGE ... like I am getting old or something
The messaging is very strong too! I was very touched and moved by the IMAGINE message.
