This was requested a while ago. I'm just now getting around to it.

Our base. Credit to Elegance Pixelfied. (Go right ahead and do anything else to prep it)

Take your original picture and crop out another base from it at a different angle like so:

Move it to the desired spot *and lower the opacity. * (Note, lowering the opacity is optional.) Erase all of the parts the cover the bottom layer.

Your end result.
