Hi Jess,
We really like your design. We have a group of 6 that is doing the judging and I've compiled their wish list below for design optimization.
Thanks,
Ryan

Remove the gray shadow below the logo
Blend the yellow and orange in the globe - maybe remove the grid lines or make the hues closer together
Use a vibrant or deeper blue for the "BELL" ribbon instead of purple - we don't want any blues to match the company "G" in the center
Make the blue person purple
Add color gradients to the people so they appear more dynamic
The font for "Technical Conference & Awards" - we'd like to see something more modern as a font with Helvetica as a fall back.
