Here is the way I did this but I'm certain there are other ways.
I took the original and made a copy.
Cmd/Cntrl + J.
On the copy layer, I went to
IMAGE > TRANSFORM> FLIP VERTICAL.
Name it flipped layer.
I selected my
Move Tool.
Hit
Cmd/Cntrl + T to enter the transform function.
Move and rotate the flipped layer into the following position.
Select your
Pen Tool or your
Polygonal Lasso Tool and make a selection
as pictured below.
Hit
Cmd/Cntrl + J to copy the selection to it's own layer.
Name this
side layer.
Should look something like this....
Go back to the flipped layer.
Hit
Cmd/Cntrl + T to enter the transform function.
Move and rotate the
flipped layer into the following position.
Select your
Pen Tool or your
Polygonal Lasso Tool and make a selection
as pictured below.
Hit
Cmd/Cntrl + J to copy the selection to it's own layer.
Name this
front layer.
Should look something like this....
Highlight both of the
front and side layers and merge
Cmd/Cntrl + E.
Name this
reflected body layer
Select your
Brush Tool.
Add a layer mask.
Use the
Brush Tool set to black on the layer mask to clean up and shape the reflection.
Again, with the Brush Tool on the canvas, sample colors and paint in any missing pixels.
Now for the hardest part, go back to and highlight your
flipped layer.
Hit
Cmd/Cntrl + T to enter the transform function.
You will have to work the image into something similar to what I have in the following image.
Right click on your canvas while in transform and use any or all of the transform functions,
Scale, Rotate, Skew, Distort, or perspective. ( I did not use Warp)
This is how it comes out.
Next you would add a layer mask and use the Gradient Tool with a Foreground to transparent preset
to fade the reflection.
