I moved your post over from the poorly named Community Help forum, which is for getting help using this forum system, to a better forum, Stock.
Your pictures are to small to get a real apreciation, but the last one would need some colour correction and I suppose the histogramm is not equilibrated.
I seem to be getting two similar images and another. As was highlighted the images are too small for proper analysis, however what seem to be common is poor white balance. The first is too cool and the highlights too bright. The other has a blue color cast, hence showing blue. For better analysis, you may upload larger images.
