I like your entry #84 and #85. The edges of the gear shown in the logo look very rough compared to the gear shown in #96. If we select this design (84 being the white background version and 85 being the black background) would the image provided have clean edges?
Yes. I am familiar with the problem, that is why I posted version #96 so that you know that more polished edges are no problem. It would be an easy fix. I also like the flow of version #84 more than #96.
Also the dynamic blue swoosh in the logo repsents the letter "D".
