I like the changes you made, but still think it could look a bit more high tech. take a look at the entry I have ranked #1. What I like about it, is that it looks very expensive and elegant. I'd like to be able to combine the two together with the people idea to the left, but still have the high tech 3 dimensional look if possible.
I like entry 154 and 153, but I am not a fan of the font and the spacing. Can you look at the font of the top ranked logo and use something more similar to that? Also, instead of treating the color with a fade shading, can you make it more of a light source, glimmer? I hope that makes sense.
