Grounding and layout of dual LM3886 PCB

When I don't have much knowledge about layout and grounding, I attach some photos in case anyone has experience with these.
One PCB is marked ZERO ZONE and the other is from Douk audio (sorry if it's wrong).
The bottom side is mirrored on the photos.

If the card depicted with components becomes relevant, I will replace some of them.

Thank you in advance!
