Hello CH: Here is a new idea. The logo is a synthesis of a moving person made from the mix of different letters. This symbolize the speech and the movement of people when they are speaking in public. Thanks! And wait for your feed back.
I kind of like the 3rd ranked very elegant design. But I don't like the image at the top. Not sure what it is. Maybe another symbol. It looks good at a glance, but it's not the image I need. Thanks
