A Window in the Background

Something with a little difference again (and fun)!

1/. You need to find a subject. In this example a girl was used.

Then a window was added.
The image size for the girl was 612 x 408px.

2/. Using the window as the background the-girl was copy/pasted over the top and moved using the Move Tool into place.

3/. Now the work begins:

Using the Edit/Free Transform Tool, resize the image of the girl into place.

4/. Reduce the Opacity to lighten in the image.

5/. Copy paste the image into the other window panes.

Here's the result:
