Step 12 Now to synthesize a reflection in the TV screen. Select your elements that are immediately atop the screen, copy the layers Cmd/Ctrl+J, and then Free Transform (Cmd/Ctrl+T)>Flip Vertical, now move the element down so that it touches the bottom of the original. Lower the opacity to anywhere from 40 per cent to 60 per cent and softly erase away the reflection, leaving the sections near the top untouched.
Step 13 We need to add some dimension to our model. Copy her layer Cmd/ Ctrl+J, and in the Hue/Saturation Palette Cmd/Ctrl+U set the Lightness to -100. Set the layer behind the original model, Cmd/Ctrl+[ . Go to Filter>Blur>Gaussian Blur and set the Radius to anywhere from 6-8. Now for some trial-&-error. Erase the newly made shadow on the right side of her body and in places where no element is immediately behind it. Just play around until you get the look that suits you.
Step 14 At this point add in your own elements, think of images or shapes that correspond to the feel and theme. To enhance the look, select the top layer and hit Cmd/Ctrl+A, Cmd/Ctrl+Shift+C, Cmd/Ctrl+V. This copy/pastes a merged layer on top of your composition. Scroll through the Blending Modes and adjust opacity to give this piece the look you want. You can also do an Auto Adjust on the Levels, Cmd/Ctrl+Shift+L. The composition may not look entirely balanced or have too much dead space. Try framing it within a smaller canvas size for a more interesting aesthetic.
