Composition would have been stronger with nothing under the bottom shelf. Hate to nitpick, but I also wish the object on the brick wall in the bottom right corner was not there. Otherwise, interesting picture! 6
I think you would have benefitted from a slightly tighter crop, removing the corner of the wall on the left, and the light-switch on the right. I also think you needed to either include the clutter under the shelves, or remove it completely as it's leading my eye out of the picture..
crop it a bit tighter - lose thing on lower right and left wall edge onleft side. if one or two things were color on the shelves - the hose, or the cat pic maybe. crop the bottom a bit too - lose the handle ends. perhaps raise midtones and sharpen a bit. BTW, i like it.
