Initial Logo Ideas

I liked this ideas it delivers the concept of bringing the four cities together. I think the four ends are evidently representing the four cities and then bringing them all to one point. I am not too sure on the colour scheme but I think this can be worked if chosen.

From research I found the idea of overlapping fonts in a CN would be a clever idea as its bring the four cities together but not taring them all with the same brush so they all will have there own colour.

Again these are the same concept... I believe that the black is not as effective as the colours as this doesn't show any bond between the four cities. And you can differentiate totally.

This is another idea... I thought that maybe creating something that could have something to represent each city and then when they all come together they create a picture. Although a cube is pretty impersonal to this subject so therefore finding an image this could work effectively for would be difficult.
