we can have a 3d rendered image set of fantasy art, based on lord of the rings or medieval fantasy, even from shows like xena warrior princess or d&d creatures, think, the gm book has 2d drawings
we can do, in blender
a castle near a medieval town
a dreary lake
various dragons and stuff like elves or gnomes
battle scenes between armies
noble princesses, both warrior and vanity
magicians, wizards, warlocks
fields of exotic plants near medieval scenery
hopefully these can be super detailed and rendered in cycles with great lighing
maybe you can release these some fall? maybe fall of this year?
and some gnome-terminal background art would be nice, or a new, modern font like sun did for solaris
here are some additional themes for wallpaper: space, space fantasy, upscaled and remastered classic art for 1080/2k/4k/8k, and custom 3d characters for a 3d wallpaper, kind of like a mascot, or you can base some wallpapers off artists like andy warhol
good luck!
