I like the human treatment because MLM is all about people... could we make the people a little shorter overall, and do a little less color? Or play around with the people theme? It's very clever.
Here is a much simpler and professional play on the people theme. I think the people actually being the graph and showing growth speaks very well about what your about. The arrows add interest and detail to the icon and also restate the theme of growth. | entry #18
