This photo was rejected for a yellow tint. I'm sorry to say that my editing skills PS Element (7) are limited beyond the ANet tutorial. Is there away to improve this photo without screwing it up?
Yeah there is a bit of yellow cast in there. That should be easy to fix, provided you have the unedited TIFF, Just go to the Color Balance window and add a some blue to the shot.
If you have a saved PSD file of your fully edited shot, you could just add an adjustment layer for curves (Layer -> New -> Adjustment Layer -> Curves), and then use the curves to remove the yellow (though you'll have to gauge that in terms of RGB). That way you don't have to do any other work over again.
