A quick bit of colour correction, since the the strong green / yellow cast stood out to me:
Rather than my normal method (using the Levels tool) I took a duplicate layer, applied a heavy blur and then sampled an average colour. I created a new layer in that colour, inverted it (resulting in blue), set the mode to overlay and then pulled down the opacity. I wouldn't call the result highly realistic but it does give an interesting tonal treatment.
I also applied some high pass filtering (as discussed
here).
