#56, #54 I see what you are trying to do to revise slightly the logo to give it a different twist but not sure I want to go that far.
#55 is maybe interesting because the logo has seem to become one with the PMC. I don't think I really need to see the white line through the top, it's not really needed. I like the typeface used in this concept. I'm wondering if COMMUNICATIONS might be a little small for a business card size, but I like how it is justified with the MC and the purple line leading up to it. For now just remove the white line and let me think about it a little more.
#58 The logo just looks odd to me oriented in that direction.
you might want to reload #81, #82, #84, I don't see them anywhere. Not in your design section or in the main section. It picks back up with someone else's entry with #85.
