So this is NOT a lake????
It is the WALL of a BUILDING right in Los Angeles?
If you hadn't told us, I'd have gone with the others thinking this was a very still lake, with the horizon in an unfavourable part of your picture, i.e. right in the centre...
Yes, it seems like EVERYTHING has been photographed by now, but everyone interprets things in their own way, provided they give their photos some thought (not all do that, but most of who come here sure do that!), so there's no going wrong in photographing flowers, landscapes, seascapes, cityscapes... again and again, I think.
