Very curious shot. It's like a picture within a picture.
Nice crop, it's a bit of a pity that the triangle on the road top right didn't quite point straight out the corner of the shot, but the positioning of the van is great and the shape made by the underpass is good. There is a nice diagonal formed betweeen the triangle on the road, the van, the people, and the patch of missing tiles, cutting from top right to bottom left and being intersected by the curve of the underpass. great geometry.
