Skilfully done! May I propose a theme for a future painting considering your skill at historical realism?
I can not find a single illustration whatsoever of depopulated Rome during the Middle Ages, or depopulated Constantinople after 1204, where the living city shrunk back within the walls and left a lot of crumbling ruins and giant monuments, among which agriculture and herding of cattle, swine, sheep and goats took place within the ruined area encircled by the city walls.
Not a single historical illustration of herdsmen, farmers, milkmaids or the like busy with rural activities within a landscape of urban decay. The image is such a striking one, that I'm surprised no artist through the centuries ever tackled it, if Google search is to be believed.
Masterwork series, that. Yes, something like Cole was what I had in mind, though more historically accurate if possible (or going the fantasy route if that is more desired; Cole did this quite much, like so many other artists, with his take on antiquity), and with human perseverance even after the downfall. The imagery is so strong, that I'm surprised no one has ever illustrated it before.
