There is a issue with your colour balance mate.
The colour green doesn't appear often at all in space.
here is a rendition that i have done in the last few months for you to reference off if you would like.
Keep a eye on your histograms to align the RGB channels. use Levels in Photoshop if your using that, by gradually sliding the black point and white points in and then using the grey point to boost the data thats there.
do this to all three channels seperately.
That is called Linear streching
Next use Curves, thats your non linear streching in where you can hold the back ground and pull the mids and highlights up.
good luck and keep going
