thanks a lot for your great submission #208. It is really something different compared to all the other drafts. I like it. It looks a bit like a nerve-system, right? Could you try to alter #208 in a way that you show something "eyecatching" (e.g. something that fits into the icon style-wise) in the nerve-system icon? The idea of #207 with the white element looks cool but still does not hit it on the head...
Because the contest is in judging mode, only the 1st place entry can submit revisions. If you would like to see the changes you requested, You would have to rank my design #1 while I upload the revisions. Thanks for your interest. Glendon
