ok you have the data in there, just need to process it out. I am far to inexperienced to offer much in the way of help, but i will have a fiddle and see what i get. curves and levels will need to be adjusted

I agree with Houghy, need to be a little more careful at extracting the data. Its all there, but appears rather washed out. Simply raising the black point using levels may provide a desirable result. It would certainly provide more contrast and richer colours. Failing that, rework the original with curves, but don't stretch it too hard.

Its better to push the data hard in the initial stages of processing so you know what its capable of. I often process a heavily stretched rendition of an image. Then refer back to it while reprocessing the same data so you can visualise the weak points. Emphasise the good, mask the bad. A iterative process. Keep at it.
