#7 - I like this because it is related to our previous year logos. I would like to have the year and the city added. I like the geometric pieces. I like the way the words are different colors. I'm not sure what the earth is made out of, but I do like that there is more than one science represented.
Thanks for the feedback, I'm happy you like the design! I will certainly add the city and year to the poster. The design is intended to represent/combine sciences in a visually abstract way. Please let me know if you would like to see anything else... thanks again!
#9 - I would almost rather see the city and date copy in the purple part. The imagery is maybe a bit too abstract. Also, it there a way to add life science or biology?
