There wouldn’t be any visible depth of field at that scale. It’s like photographing mountains from a distance, they would all be in focus.
So whats making that show feel off? Or is it just me.
It’s not easy to show distance in space. If something is further away it will just look smaller.
In your first image the star destroyer is probably actually in front of the SSD, but because it’s placed higher up in the frame you get the impression that it is behind the SSD which makes it look too big. Unless the objects overlap it’s difficult to tell which one is closer.
