I know many of these (Floox, Lucyla, Truck-kun art, Waifulover, etc) use Nyantcha's style as a reference, but still seems different. Maybe they mixed two artists' styles in the prompt? Still trying to figure out who, though...
@rig.uki looks more a mix of other artists like it looks similar to YD's shading and for some reason you can make out cutesexyrobutt's patreon name like in page 7.
