Subnautica has some nice scenery, though for a painting I’d probably go with something like the safe shallows where there’s plenty of sunlight, or maybe the underwater islands or the kelp forest.

MInecraft would have a lot of possibilities, particularly with some of the new terrain generation for mountains as well as the cherry tree biome that was recently added. However, with each world being generated randomly, there’s no definitive scenes that would be instantly identifiable as Minecraft. So you’d have to rely on making the painting sufficiently blocky and/or replicating some of the terrain generation quirks like the occasional floating tree or lava flowing out the side of a hill and things like that.
