Altho the picture is what it is, I always try to dissect pictures to see how they may have been not perfectly framed, captured, exposed.
Looking for the center of interest, it clearly must be the girl's face, bathed in the light from the lamp above.
But her face is almost pressed up at the top margin.
The tilt can be excused because it is a grab shot but the fact is that we are aware of it and then must 'excuse' it.
There is also a bright pole growing out of her head.
So what if the tilt were removed?
It seems that the stairs and verticals frame her nicely but there is a lot of space at the bottom that isn't balanced by any space at the top.
I think if she were lower in a larger, uprighted frame and that bright pole removed, she would be at a stronger place, her face would be bathed in more light and not pressed against the margin, the tilt would not be annoying - and it would overall be a much stronger picture.
