Step 7 Add a new layer and fill it with the cube pattern you’ve just created. Duplicate the girl layer and apply Edit > Transform > Skew to this. Distort the image so it follows the angle of the cubes – for this image I used the left sides for reference. After that go to Filter > Blur > Gaussian Blur. Use 10px for the Radius.
Step 8 For the next step, you’ll want select the left sides of all the cubes. To do this, select one with the Magic Wand tool (W), and go to Select > Similar. With the marquee selection active, click on the distorted girl layer and go to Layer > Layer Mask> Reveal Selection.
Step 9 Repeat the process for the other side of the cube.
