At this size I see no fringing...
. I do see a little bit of purple shade in the original image ... but I think that is more purple cast rather than fringing ...
You will always see problems in any kind of image once you start pixel piping (even on those already in PEG).
If you do lighten the foreground, I wouldn't do it too much. As other said, you do need that contrast ... my comments were merely on composition.
Don't get too down about it though, your image is very good just the way it is anyway. And improving it for the liking of PEG judges will be an impossible task, unless you re-take it.
