#1 I'm not sure I like the particular body/person image, but a very cool use of the body as the "X". The streamers(?) add a great motion/celebration feel.
#2 - Another very cool idea. I was wondering if we would be able to play with the axis imagery, but I don't think this is a "go". If we present images of people, even stylized, they have to be really positive. In entry #1 the person had a lot of energy and spark (good) whereas this one is too stiff and staid.
