Yeah, it looks like the skin tone is slightly different on the new one, but same figure, which makes sense, those big ones must hurt them if they don't sell enough so make more money off the old work.
Repainted my NECA Godzilla 2019.
Before
After
Redid the eyes, cleaned up the gums and teeth, redid the inner mouth, there was a lot of the dark skin tone still showing in there so I redid it and made it more solid coverage inside.
One improvement over the 2014 is definitely how the tongue shows more like the 24" HTT 2014, my 12" HTT 2014 barely shows and I just like something about the tongue rolling and being visible.
