How did you do it? I tried with the cloning tool, but my try is not nearly as good as yours...
I think yours is pretty good for the top portion with all the glass. For me, the floor turned out to be the easiest part. Here's what I did:
1. Copy as much of the floor below the woman as possible and paste into a new layer (image 1 below).
2. Click on Edit>Transform>Flip Verticle. Move the flipped image down until its top edge just touches the bottom edge of the original photo. Use Edit>Transform>Scale to stretch the bottom all the way down. (Image 2 below)
3. Click on Edit>Transform>Perspective and widen the bottom of the new layer until the perspective matches the original floor (image 3).
4. Apply curves and gradients to the new area to get the shadows to blend smoothly.
5. Use the Spot Healing tool to eliminate any particular spots where it is obviously copied from the original area. (My final version could use a bit more of this.)
I did essentially the same procedure for the top half of the image, but the 'perspective' step was not needed. The problem up top is that the new layer---after the verticle flip---is very obviously a mirror-image reflection because of the glass shards. I initially tried to fix this with the clone stamp, but had better results with the Patch Healing tool, which I used to grab random bits of glass from elsewhere to eliminate any obvious mirror-image areas.
