I think this shot works pretty well compositionally, but the harsh lighting somewhat interferes with my reading of the photo. One thing I noticed immediately: the boot looks a bit washed out, perhaps secondary to lens flare.
I can't figure out what the elements in the top right 1/5 add to the image. What do you see here? I see them as the third point in a triangle, but I don't see their relevance, and they lead me away from the main subjects. Have you tried a crop of just those elements? I think the sash around the drapes matters, and I certainly wouldn't crop that, as it implies an abstract waistline.
I think that if you reshoot this in less contrasty light, or perhaps repost as a B/W, your image would show more strength.
