You got pretty close! :) They are completely digital, but painted using brushes I made from photographing charcoal on paper! So I’m very happy to hear that you couldn’t quite figure out whether these pieces are fully digital or not, as that’s exactly what I was going for. The floor in [redacted] has seen some additional editing (perspective transform), which is probably what pushed it more into the digital realm.

And thanks! Your kind words are much appreciated! :)
