through the ceiling

If there was this bit across the whole sky... I reckon it would be a bit weird, but interesting... I mean, it's the feeling that one is caged, isn't it? I feel as if that gets to us most, because we can see how blue the sky is, and we can see the limits (or rather, no limits) and yet we can't reach it fully because of this...

It's pretty powerful in that sense, if you do interpret it to be that way.

The framing is slightly off, but it's not that major a point here. Great perspective.
