Gimp how to make a layer for inserting images?

Question

GIMP

As far as I know, this is a standard task for Photoshop, but I don’t understand at all where to dig to implement this in GIMP. Suppose there is a picture:

You need to prepare a GIMP project in such a way that you can insert a picture with the slightest gestures, and it succinctly poured onto a piece of paper in the hands of a girl, already with a distorted plane. What tools are responsible for such implementations or GIMP functionality is not suitable for such manipulations?

Answer 1

, and naturally showing what happened and a bonus
