Yes, too much green in the fleshtones...that is quite often an issue when photographing under or near large expanses of trees...using an orange-hued filter over fill-flash, or over the lens when photographing can help eliminate that problem. You missed the focus in the first shot, which is evident on FLickr when looking at the image larger than a business card...
In post processing, I'd say open the files, go to selective color, pull down to the yellows, which will tend to be the caucasian skin tones, and then ADD some magenta, to cancel the greenish pollution in the yellows....also, while there, stop by the REDS, and shift a couple of sliders a few points one way or another...maybe visit our friend Cyan, maybe give a tiny wazzup! to magenta for a second.....should be good to head home after that...
