#83 - I see it looks like a central person which is level 1 privacy. Then the flare on the left represents level 2 which is the personal groups you decide to share with. The flare on the right representing what you share with the public as it starts to wrap around (including) the level 2 (since level 3 is a bigger audience).
My concern with the icon is that it also looks like an eye, which will be the most common interpretation by the public. Maybe it wouldn't be misinterpreted as an eye if the two flares were rotated in some way either 2D or in 3D
Also the color of the nexul name should have a more uniform gradient, and be filled in with color - one color for the border (maybe black) the the filled inside either blue or green (from the brief). Then after the shapes in the icon are rotated per above, the colors may look good in either blue/green combination or the blue/orange combination. the slogan coloring is either fine as is, or should be the same as the outline of the nexul name (bottom half if a gradient is used).
thank you very much for the feedback.. here are some variation designs to meet your requirement, hope you like them.. don't hesitate to ask me if you have any feedback or request.
#99 - designer flatworld submitted #89 which has the same ribbon person concept. Looks like he barely beat you to that concept, at least for this competition. I'll leave it to the two of you to work out if one of you has prior rights to that from another contest.
#91 - better. But I was thinking more of a non-uniform rotation of each flare so that the points were not on exact opposite sides of the center sphere.
