For entry #1 we like the inclusion of people, infrastructure (assuming it is a road - perhaps it would be little more distinct with a median down the middle), and water. Would it be possible to add a graphic for energy (such as a wind energy generator)? In addition, we would like to see how the logo would look with a graphic for a city included - e.g., a city outline in the backdrop.
We have extended the contest a couple days to get some additional feedback from other members of our group and to discuss a couple small changes. Would it be possible to change the title from "RCN" to "NSF-RCN"? Your most recent submission(s) - in particular #60 and #61 - are in discussion as one of three designs to be awarded the prize.
I uploaded pictures but have to wait to be accepted by the site administrator. Please let me know if you would like to see more changes, I'll be happy to help you.
