body of water, possibly a canal or river, with calm, rippling water. On the left bank, there's a grassy embankment leading up to a concrete retaining wall covered in graffiti. Above the wall, bare trees are visible against a cloudy sky. A bridge, also made of concrete, spans the waterway. The camera appears to be positioned on a boat or other vessel moving along the water. The lighting suggests a gray, overcast day. As the camera moves, more graffiti covered retaining walls come into view along the bank.
