Great designs! I especially like that "Virtual" and "Spokespeople" are on separate lines and the character on the left. I like the blue from #12. Maybe also try a version with rich purple like what is at the top of the website
http://www.monster.com/The mascot/character is a great start, and I like the idea of a "thought bubble" to indicate communication, but we think the character could be improved by being more human-like.
We like that you are creative and submitted the dotted lines character, but we don't think it will work because it isn't clear enough what it is.
Thanks again!!!
