Here is my final logo entry. I had tried to throw in the skydome and the york hotel on either side of the Bank of Montreal and Scotia Bank, but it didn't look right. First the skydome with it's round shape took away from the buildings rising straight up, which created imbalance on both sides. Second the buildings right now are rising up high into the clouds. By putting those smaller buildings in it, it gives a threshold of where the ground is, thus shrinking all the towers.
I think this is the best version, and it is completely balance on both sides. Everything is rushing up from the font, which is what I wanted.
I also wanted to display this logo on the default color band of this forum to show you how seamless this logo is on different surfaces.
Number 1 is stunning but it really doesn't say anything to me (other than we are a bunch of Skyscraper fanatics... which is true).
Might be a little heavy of the tower theme given the mandate to speak about many things beyond towers.
Number 2 is great... friendly but sophisticated enough to be taken seriously.
I'm suprised you are only going with one colour variations though. We can always do one colour versions when we need them, but I think you should recommend a two colour treatment (image/font) which will be far better for web and printed materials.
Your density/SD combo might work... kind of weird but very democratic!
I know...I really wanted to work on this but at the same time have been really pressed for time as it is the end of term and I also have other stuff to take care of from paying clients. So I thought I'd just put what I had.
