This image was rejected for technical issues. Can anyone tell me why? Thanks in advance!
There seem to be a white balance issue. The photo seem to be a bit blue, meaning it is too cool. Add a little more temperature, so that the white looks white. At 100% magnification you should be able to see better for the adjustment.
It is because of white balance, the hand should be more pinky, so Jacquelin has said, the overall cast of the image has a blue cast. You need to warm the image up by increasing your temp slider a bit and increasing the tint, so the hand is just a bit more flesh coloured.
