Thanks for the edits, logo #1 and logo #3 designers. Overall, I really like the changes. Regarding logo #5, the tag line appears more legible and the circles do suggest something more about people. I do worry, however, about the logo being a bit too busy and the circles and the rest of the logo blurring together when printed on promotional materials or when inserted into website/powerpoint slides using backgrounds other than white. Regarding logo #4, I like the green-gray-black color combination and the logo having the look of something people-related. I don't know if the gray color in the company name will look washed out a bit when printed on promotional materials (or inserted as a graphic on website/powerpoint slides) on background other than white.
FYI, I'm ranking the logos on my own right now. Before I make a final decision, I will ask a few other people to provide me with some feedback. I will, however, make the final decision. Also, FYI, I sometimes refer to my company, in proposals and other documents, using the abbreviation BHRC. Just thought this info might spur some additional thinking. Thanks again for all your efforts.
