With some image stocks, image adjustments and filters, we can create a realistic floating landscape. This tutorial involves cut and pastes, lights and shadows, and proper blending.

Open the sky stock and duplicate it. After this, open the farm house and make a selection out of it (the house, trees, and grasses) by using the Lasso Tool. Copy and paste it on our background layer. Apply Free Transform to enlarge and reposition the image. Set Mode to Darker Color. It should look like this:
What we will do here is to make it appear that the farm house is something like uprooted from the ground, and we have to make that realistic. To do this, erase the lower portion of the grass first.
Now open the third stock image (i.e., the eroded soil), make a selection from the tip of the ground downward, with the roots included. Copy, paste, and apply Free Transform. And this is how it looks now:
Erase some of the portruding parts of the eroded soil. Take the Burn Tool (soft brush: 15px, Range: Midtones, Exposure: 50%) and apply at the tip of the grass to blend well with the soil. Apply the same to the soil as well to have a better contrast. After this, apply Gaussian Blur a bit on the soil’s edges to soften it a bit.
We’ll make image color adjustments some more here because the soil is too bright and doesn’t look real to blend with the house. So, go to Levels (Image>Adjustments>Levels) and apply the following settings:
Almost done with our main image. It’s time to make a motion effect of the image as if it is falling or rising up, depending which direction you prefer. First, merge layers down to the Background copy layer, then apply Motion Blur (Filter>Blur>Motion Blur).
Add falling soil particles below the image. Make a new layer group (Layers>New>Group) then make selections out of the eroded soil we used earlier and paste it. You can name the layer group as Falling Soil or anything you like. Apply image adjustment levels and appropriate motion blur like we did above. The outcome looks something like this:
Add falling rocks to spice-up our main image. Make a new layer group and name it Falling Rocks. After this, open the rock photo and make some selections, copy, and paste them beside, on top, or below the image. Apply image adjustments and filters like we did previously. When done, merge group. It should look like this one:
Merge all visible layers now. Duplicate the existing layer (the Background layer). Apply the following image adjustment settings:
Finally, set blending Mode to Soft Light, Flatten Image, and we’re done!
Here’s the final result:
