Yeah, the highlights may be too green.
Also, if you want it to make like film, shouldn't the contrast be increased a bit? That is, a more photochemical-looking pushing of highlights and shadows - not the digital crush/blowout we complain about. Film prints do not have dulled highlights like your "after" pictures are showing.
But this is still great work, I agree about the gas giant planet now looking like a painting out of the OT.
