Very nice signal, maybe a bit too dark in the background?

@vincent-mod
Thank you!

Hmm, this might be a screen cal/difference issue? I mean, it's not clipped for sure...
I still see the BG differences and features.

Sorry for the delay. Yes partly, if it's not clipped that is good indeed. I personally simply prefer a slightly brighter background, but it's a great result nonetheless!

Yes of course, we all have our creative differences 🙂
The lower part of the photo below the "wall" is always brighter, the upper part is always darker, since it's kind of "blocked out".

I wanted something a bit dramatic, since the wall is very emphasized, and bold... That's partly why I went for gentler tones, less saturation, since the structure itself was very pronounced already.

This is for example, an early "playing around" version:
