What?? How does your layer breakdown facilitate parallaxing?
I dunno if I should be speaking for him, but I suppose he's simply dividing the background into sections of depth. It might not look right, but I'm sure he's working with it in a way that he know will work.
I know I shouldn't be speaking for Mathias, but here goes nothing.
We're familiar with parallax scrolling, but aren't things like skies and clouds set up in straight lines to give the illusion of endlessness? Some time ago there was a user that was making some amazing parallax backgrounds. Maybe they were just endless backgrounds... regardless they follow similar rules (of thumb).
Though I guess this could work because mountains are frequently used on parallax backgrounds.
I guess we'll have to wait and see how this works out THEN address the issues.
Mush, I'm a little worried about the dithering you're doing with transparent. If your light golden dithering goes over one of the darker colors then it might look ... off. But I would like to see some dithering within each parallax layer.
On behalf of Mathias. ;]
