I am sorry, I must have looked too fast, I didn't see the one with footprints. Could you put them again ?
#27 is too perceived as too weird, with the web in the middle of the city. The idea would be to work more on the city side of your logo, with more colors, a green and blue city (see Nantes on google pictures), water and urban forest, and people in the city (with more diversity wheel chair, bicycle, ...)
is that possible. It could be a city seen from the sky (googleearth Nantes, France), with colors, and the heart beat, that we like very much. Is that possible to go in that direction ?
