Oh my goodness I feel I am being really stupid here. Something about this picture is really appealing but for some reason I feel I am struggling with what you are trying to get across in terms of closing.
My thoughts (for what they are worth)
1. Is it something to do with the word casa? But I only know this as being the spanish for house rather than closing
2. Is it to do with the thin band of focus?
3. (My preferred route) is it to do with the fact that a full stop (or period if you are American) closes a sentance.
I guess the later with it being accentuated by the focus line...Hope I am right. ANyhoo regardless of whether I am or not I have to say great shot and I have really enjoyed looking at it trying to work it out. Super textured feel 8
