This is excellent. Would like to see the "insurance & financial services" be a bit more pronounced and more visible. The circle with the buildings and river is cool, but I'm concerned that it might look a bit like the Obama circle which might turn some folks off. Great job.
I really like 48, 49, and 57. The only change I would want to see made would be to have the words "insurance and financial services" stretch below the picture and the word "Rivercity", so that they are larger and more visible.
