How the 2010s imagined the future, as solarpunk digital concept art filling the whole image: a dense Korean apartment district retrofitted for a green future, the tower blocks covered in terraced gardens and solar panels, rooftop wind turbines turning slowly, a quiet tram running along a tree-lined river, bicycles and pedestrians on wide shaded paths, community vegetable plots between buildings. Painted in clean digital brushwork, soft golden morning light, lots of greens and warm whites, hopeful and calm. The upper third is clear sky with a few birds. No real city skyline, no text, no letters, no logos anywhere.
