Ady, there’s some funky low-frequency color noise in the background of the shot at 00:24:35.
I noticed it when watching on my projector and it was a lot more visible there than it is now on my monitor but it’s still there and it took me right out of the movie.
The artifacts are likely to have already been there in the BD but they were brought out when you added a more yellow glow from the sun.
A simple low-frequency denoise pass should solve it nicely without affecting the overall detail. I have some great tools for this, so if you send me an uncompressed version of that shot, I’d be happy to give it a go for you 😃
