stadtvertrag klimaschutz wettbewerb

hi guys,

i've made another drawing which i've turned in for a poster contest here in Berlin:
http://www.stadtvertrag-klimaschutz.de/zum-projekt/plakatwettbewerb.html

I was trying to keep it simple again but its not as striking as i've wished it to be.but anyways, come take a look and tell me what you think!the bottom line had to be left empty for all the sponsors logos.
