After talking to a seasoned art director, I changed my top choice to your Entry number 2. We are both excited and hopeful to choose one of your designs and have an idea. We think the clean clear design of 2 is easiest for print production whereas entry 4 has text with blue all around that can cause print challenges later.
Our excited wish and likely winder of this contest is something like your number 2 entry in design and color and text. Yet instead of dots as the circle, it would be a circle of dancers of various sized bodies (some with one leg kicking up (I can send you images that express the style of the dancers with an email address perhaps from my iphone)
The director felt the image of the bodies on all the other submissions look very generic and we want to express the community of feeling good together at all sizes. (now dancing)
If you go to the trouble to do this and place the dancers in a circle like entry 2....I will likely choose this and end the contest. :)
