Is it possible for you to take the building graphics in #3 and change the scale and flatten them out a bit. We think that it is a little too vertical and busy.
Also in entry #5 if you could give a few other variations of the graphic (flatten,maybe the window detail of #3 in the "A"). Living in Atlanta Georgia, # 6 is very similar to the Atlanta Braves logo. Entry 1 &2 are bit too angular.
