Logo / App Icon for #VirtualConference 3

This was my first attempt at the logo/App icon. Since it's a virtual conference, and could be attended from anywhere, I added the globe. In essence, it shows two people shaking hands. The circle signifies that it's a global product.

Besides to the details, I shared in the other two. I imagined that the logo was being designed for a more traditionally minded client. So, for the heads, I chose to use a different color, such that the outlines of the head and the hands are visible more clearly.
