I like the iconic figure on the left. It would be nice to have a more recognizable figure that could be repeated as a theme throughout the website. I worry that the blue-green used in combination like this almost looks like a health care company's logo. It would be nice if it was a little "hipper", a little more modern, without being flippant; possibly through small touches of grey.
For entry 71: Could you play with the colors some more? The leg colors don't look quite right and I'd like to see some more choices of contrasting pairs of colors.
