I like the way you play with the two NN... the way yoy combine it. However, we need something a little more modern and stylied. Something a little different to the worldwide air conditioning brands.
You did a good job. Your Entry #10 is nice. The combination of "NN" is interesting but I would like to see something more modern; different to the worldwide air conditioning brands.
Entry #53: I really like this logo, try to maintain the light blue after the second "N" letter... And please reduce the separation between the letters of CONNOR word.
