Not crazy about the crop in number 1. Like 2 and 3, but not a big fan of selective color. WAY over-used and in many cases, it's used to spruce-up marginal photos. In this case, I don't think it's necessary because the image stands on its' own. You may want to try number two again, and use a longer shutter speed to give the background some added blur. Nice portrait light on the girl's face too. Good job overall.
