Much thanks and impressed with the speed!
If you don't mind doing another pass on the logo, I have some feedback on the logo:
1) Not a fan of using the document icon. It feels too generic.....
2) Putting the document icon in the C makes the C look like an O which could be very confusing
3) I just had an idea of doing something with the idea of "Zen" and the goal of two parties coming to a harmonious agreement that both sides are happy with
4) I'm using mostly 'Open Sans' font in my website, so I think the font used in the logo should complement the Open Sans style.
5) The logo should look good on both white and black backgrounds (maybe via inverting the colors).
If you decide not to do another pass I understand. Thanks either way!
Just finished work on the new concept.
