The colors on this image are a little muted, this can be corrected by fixing the levels, raising the contrast and maybe tweeking the saturation just a little bit.
Framing could be better (to get all her leg and to hide the guy in the background), but their faces are nice and innocent. Enjoy their getting along while it lasts, hah.
Would've been a really good shot had the colors been a little brighter and not quite so washed out. Other than that, I love the subjects and their expressions. The other people in the background kind of distract, but still not a bad shot.
