Very cool. How can you tell a boy chromosome from a girl chromosome? You can tell they pull down their jeans! Honestly, this is a fabulous shot. Intriguing colors and composition. 10
This is quite a unique entry to this category and well executed (imho). The reflections in the glass are a bit distracting (not sure anything could be done about that though).
Love the color. For me personaly, I would like to see the composition shifted a little more to the left so what almost looks like a line down the center would be a little more off center.
I like the composition of the photograph, the cropping and the tone of image. I think it captures the idea of the challenge embodies. The only thing I find somewhat distracting is the glare coming off of the glass, but I don't know if that could have been avoided and you still have gotten that angle, even despite that good job good job
