Alejandro's proposal looks nice, but it is too dark for a wallpaper. I think it would be better if the background blue-ish colors were a little lighter, pretty much as in current 14.2's default wallpaper. For me at least, too bright
and too dark wallpapers are both very uncomfortable for a desktop background. But then again, opinions are like... you know... we all have one.
P.S. Isn't funny? Salix is so ridiculously rock-stable and functioning, therefore we are talking about... the next wallpaper, since there is basically nothing else to talk about. The operating system itself has no real issues whatsoever, to the point you forget it is there, and you start arguing about the wallpaper or if Firefox ESR should be replaced by Firefox Quantum.
