Duplicate sheets several times and change their position, to make the texture more diverse. I will integrate layers with sheets on the floor and add a layer mask to remove the duplicated fragments.

Step 29

We now make flying sheets in the background. Again, Place image "burnt_music_sheets_png_by_frozenstocks-d5prud7" and simply duplicate them three times and is located at the middle and bottom of the image. Resize multiple copies to make realistic flight (pages cannot all fly in the same plane).

As with previous sheets, I merge the layers into one and added a layer mask and remove some pages to reduce their density and set the direction of flight.

Step 30

Convert resulting layer to Smart Object (right click on a layer > Convert to Smart Object). Now we can apply a motion and make changes to it. Go to Filter > Blur > Motion Blur. Set Angle: 35 degrees and Distance: 30px and click OK.

On effect layer mask remove blur from edges of the sheets which are closest to model with Brush Tool (B) (Size: 150px. Opacity: 40%, Hardness: 0%).

Create a new layer above flying sheets and fill it with black color. Set layer Opacity: 56%. At now sheets, look realistic. Because the light in this picture is not uniform and it is important to preserve the unity of the atmosphere.

Step 31

Similarly, to Steps 29-30 made a bigger sheets on foreground. All the effects and action have remained the same, only now to make a big page (do not do too many of them), and on a new layer (as Clipping Mask), apply shadow (use soft round brush with black color) on the edges of the pages where they are closer to the edge of the document. Set to Shadow layer Opacity: 62%.

Step 32

Now enhance the color in the picture detail and elaborate lighting. I am writing this now because the main objects properly in place and we can do the right lighting. Create a new group "FX" (on Layer panel click on appropriate icon) under group "Book". Create a new layer there. Use a soft round brush with Opacity: 100% and color #e8702d to paint the first stages and part of the floor on the left side of the image. Same for the right side but use color #efec43. Set for layer Opacity: 23%, Blending Mode "Hard Light".
