Although I prefer the concept of working on RGB-curves, I like the look of your new results ... except that the colors are too saturated. A reduction of about 15% should remove the effect of "green-tinge", or "yellow-tinge", or other tinging (depending on the shot), while still letting your colors "pop" (as movie reviewers like to call it). Also, the overall improved brightness nicely opens up details hidden in the darker areas.
