Howard, Nice shot. You have a green gradient that you can get rid of with the plugin below. http://www.deepskycolors.com/archive/2010/04/26/hasta-La-Vista-Green.html Also, your background has a blue bias. If you neutralize your background it would help. Attached is my version after running HLVG filter and cleaning up the background.
