To start, a 5.2 isn't bad. I can quite easily see the difference between the 5.2 pictures I comment on and the 4.8 ones. The picturee here is technically quite sound. The lighting doesn't leave us with large blown or dark areas and the texture is interesting. The composition is perhaps a bit static; everything is squared and there are no dynamic angles or points of view. The chair, as the subject, is a bit hidden by the dark debris surrounding it. If you could have, I would have either moved the chair to the other wall, or removed some of the debris right there. The picture seems to have a slight slant to the right, but that may be an optical illusion from the hanging pipe which is likely off kilter to start with.
