I hit auto levels on this picture and nothing happend. I think the colour looks too saturated and too red and green:
So i took the same image and adjusted the Hue +4 Saturation -16 Brightness +12 Contrast +2 I then hit auto levels. I then duplicated the layer and using variations blue and then set the layer opacity down to 25%. Saturation -4 Lightness +2. Then i adusted the color curves to Input 100 Output 130.
