Usually I'm huge fan of your work Andrea but this time the noise reduction is definitely too high. The screenshots I've made show a huge lack of details, it reminds me a little bit of a painting.

I don't want to be harsh tho, I still respect your work and i'm impressed by your script but you should definitely reduce the noise reduction.
