#45 is a good example of different versions of the same font, but the font isn't unique.
#2 is an example of different colors, but the colors aren't right.
I'm not crazy about any of the fonts submitted for my contest. Most are standard and boring. Some are unique, but not contemporary. At least your #47 is fairly unique. The logo without the CQ design needs to stand alone. The font just doesn't look profession enough. None of the top designs use serif fonts. In the Practical Systems Contest (
https://logotournament.com/contests/practical_systems), #50 uses a fairly interesting font with two thicknesses and two colors. I'm not sure that fonr will work with your CQ design, but it's an example. I like the CQ design very much.
I like the CQ very much. We just need to find the right font.
Thanks again.
