I like the concept of the talking bubbles. I like the colors in #16 and the Venn diagram in #17 and #18 (it shows how there may be agreement between the things people are saying).
Could you make #16 colorful, and make the overlapping area a different color from the other three bubbles? Can the MIDDLE (overlap area) be orange?
Also, is there any way to introduce the concept of technology/web to this? With only the bubbles, it captures the dialogue piece but not the SEO/web consulting.
