Hello raymer - thank you very much for contributing - much appreciated!
#66 - The logo feels a touch too bold and needs to be a little softer. A bit too big. I'd like to see the icon softened and without the white hash marks in the m portion of the icon. The lines in the icon and font are just a little too thick.
#67 - this logo doesn't make me feel energetic, but a little too passive. I will remove this one.
