I think your designs are good, but I'm not liking #51 as much as I thought I would. I still like the way the LEF looks in #15. If you could put that in a circle or a square next to the logo as in # 51, I think I'll stop asking for updates. Thanks for all of your efforts!
anything I can help with on this contest, just let me know. any designer can be placed in 1st ranked position and then tweaks and changes can be done and uploaded during the judging stage. just FYI
