I'd crunch it up a little more with a curves adjustment. These children don't look healthy and stronger contrast will help. Also push the reds toward a slightly more orange tone. They look too purple. There's also still an overall purple tinge which needs to be eliminated. See the included 3 minute quick shot of mine. Not perfect and requires more tweaking (too much yellow now, see the lips), but I think it better represents the feeling one would want to convey.
