All of mine are self-made, so this means that the background by itself sometimes looks a bit odd. Each wallpaper is built to fit a specific Puppy.
Some share a common design, but with color/tinting/saturation modified. Some use an entirely custom layout, for that Puppy AND NO OTHER.
Like this one I've just built from one of the concept wallpapers for the upcoming Windows 12. My 'daily-driver', a 'lite' spin on BK's older Quirky64 April'7.0.1, has had the same look for more than 2½ years, so it was well overdue for a 'make-over':-

I showed it in the Desktop screenshots section a day or two ago, though the tint has been changed, and the saturation dialled down a bit (that purple was too "in-yer-face" for my liking..!)
Those panels - MY answer to 'docks' - all get populated with icon launchers, or sysinfo GUIs. The circle bottom-left is where my animated puppy endlessly romps across the screen. "NetSelect" and "GoogleMaps" are the positions for two animated GIF icons, which are coded to ACT as launchers; one launches a Chrome 'window', the other the multi-selector GUI for all my internet apps.
