The road markings include a bicycle and pedestrian symbol, which is common in Europe. The landscape features a canal or river with a bridge, typical of Central European waterways. The architecture and vegetation suggest a temperate climate, likely in Germany or a neighboring country. The overall aesthetic is very characteristic of rural or suburban Germany. I am moderately sure this is in Germany.

The graffiti style and the concrete bridge structure are very common in urban areas across Germany. The blue circular sign with a white bicycle symbol indicates a mandatory cycle path, which is standard in German traffic regulations. The overall environment, including the bare trees and damp pavement, points to a late autumn or winter scene in Central Europe. I am fairly confident this is in Germany, likely in a city like Berlin or Hamburg given the heavy graffiti.
