Me neither, it just... I don't know, maybe the disproportion of the doors plays a trick on my eyes or the lines are not entirely parallel and vertical, but somehow I need the urge to tilt my head. But don't mind me, its an awesome deviation - instant fav.
Oh yes I see indeed, the door is quite old and parts tilt, that was what was tricky also in fact, I thought when shot. No worries, it's just that I was not sure of what you were meaning (English is not my first tongue and google... well, you know ! )
