Bear in mind that the 3 Challenger Men/Mr. Challengers are splitting the vote based on periphery details. These three should be counted as one, and the surrounding parts should be hashed out afterwards.
Besides, the wasp is just a little to similar to the SuperBee... but Challenger Man is all business. Looks like the kind of bad mother who would take a can of bug spray to the lowly wasp.
To add to all that, here is another revision that I made, just while messing around on the PC. I think for Challenger Man to really work, someone with considerably more artistic talent than I (either real or photoshop) will have to work the picture so that it fills the circle, then add groovy psychadelic 60s type text above and below saying Challenger Man. Right now, with so many concepts for the design of the "Challenger Man" logo abounding, I propose that we count all the votes for Challenger Man together, then if he wins, hash out the circumstances in which he will be displayed.
