Looking at the creepy "art" showing children and a pool/shower/tiled room, I think it's not a pure painting.
I think the "artist" is working from real photos, projected on canvas.
I just don't think the "artist" is particularly skilled, and uses the projection of photos as a "paint by numbers" method of creating their work.
Nobody is going to have multiple models (especially children) sit for work like this "artist" produces.
If this is in fact true, subtle details like black tiles or shapes of tiles or patterns may indeed reflect a specific place.
I'll ho a step further and assert that paintings of actual victims is a way for pedo/perv art collectors like Tony & Heather Podesta to have their actual perv adventures memorialized in paintings on open display.
Hiding in plain sight.
