I built this small showcase of low poly ruins, the effects are from the toolbox but the constructions belong to me - More examples of my work in Talent Hub :b
Looks neat. Oddly enough, I like that flooring.
I would recommend adding some more bits of rubble, maybe some more foliage, like bushes or grass or vines across the floor and pillars. Assuming this is an old, unkept ruin.
Maybe some arches as well, to fill in the “ceiling” a bit.
This is all going on what these three images are showing.
