I think you have done a great job with the overall contrast...but the color is still off... Try setting a new neutral on your current version and see if you can get rid of the blue in the frame....
To be honest - the cast here is quite annoying and was caused probably by different colored items near this object and then the light came back from them to the object.
I guess the easiest way will be to re shoot this picture...... :D
Many have tried the re-shoot chant.... ;) This was a once in a life time trip to SE Asia by Mike....I'm pretty sure he would gladly go back and re-shoot for you but.....
This is one image where you will not get a perfect result at this level...just make the best compromises you can...
