Lost location

Having finished my last commission I found myself with studio time to fill and nothing in particular to paint. I found a photo on the Internet and thought I'd have a crack using a palette knife and crescent board. That absorbs the oil from the paint very quickly and thus dries fast. Here's the result. It's only small, around A4. Problem is I don't know what to call it because I can't find the photo again. Anyone recognize the river and backdrop?
