It looks like it was shot through a window, for sure. I mean, I can tell it's shot through a window. Often, I like to be able to literally SEE some reflections on the window surface, which hopefully add to the shot. I've shot through windows a time or two; sometimes in post-processing, an adjustment or two here or there can make the window surface and its reflections suddenly become MUCH more, or less, visible. Usually it's the curves, but sometimes it can be something like dropping the blacks down, deeper, which will all of a sudden, just BOOM! makes the lighter, reflected areas suddenly MUCH more-visble.
It depends on what you want to achieve; sometimes the idea that you are seeing through a window adds to the shot. Something makes me think this shot is one where the window-peeping effect can be increased, and it will look better. I'm not overly fond of this picture, but it's not bad either, and it makes me think, "WHat the heck kind of place is this? Old movie theatre chairs on a flat floor? Looks like maybe a Bayou-country meeting house or something. I dunno. Huh. A bit different."
