Lots of yours are great! I've ranked several. I know I said black and silver, but do you think if we added some red or another color it would make logo pop?
#2 and #3 let's try to incorporate some red For #2 maybe red lines and for #3 maybe the NN in the middle in red? Also, please be sure to keep original versions too. Thanks!
I apologize above for #2 I meant #16 (red lines) For #2 let's maybe make that dot in the middle red? And then do another version where the dot in the middle is red and the concrete design is also in red?
