Add depth to mixed-media collages

08 In addition to the layers of texture, I’ve made some vector blobs with shaded edges that create a gradient effect. This was done with a bespoke brush. To do this, open a new document and use the Radial Gradient tool to create a simple black-to-white gradient. Go to Filter>Add Noise and set this to about 100%, then hit OK. Select the Brush tool then go to Window>Brush Presets. From the drop-down menu at the top-right of the Brush Presets panel, select New Brush Preset.
 

09 Go back to your main illustration and, using a new vector blob, create a new group mask. Fill this layer with light grey by going to Edit>Fill. Then, using your new bespoke brush, start adding shaded areas in black.
 

10 To make the composition more interesting you can add small areas of texture using the paint marks you created earlier. To do this, open the texture you want and drag the layer into the desired group. In the bottom of the Layers panel select Add Layer Mask. A small box will appear next to the image box in the Layers panel. Select this, and then select Brushes. Select black in the palette options, and mask out any of the texture you want to hide. Play around with the opacity to get a good gradient.
 

11 Keep experimenting with these techniques to layer up your collage. Try adding in vectors with gradient areas, and playing around with the opacity settings to make them feel translucent.
 

12 I decided to add some collaged imagery to the illustration to make it feel more interesting. I did this by scanning and cutting out imagery using the Pen tool. I then copied and pasted it in. To make the flowers feel like they are emerging from the depths of the pit, I added a new layer and, using the Brush tool, blended some black over the top.
 

13 To give the illustration a final touch of depth, add some small wispy vector shapes and cover them with a gradient so that they feel smoky. Create the small wisps in Illustrator and paste them into Photoshop. Add a layer mask, as in step 10. Instead of using the Brush tool, select the Gradient tool and gradient out the mask.
 

14 Now the ‘hair’ is completed, I’m going to add a face. Cut out your desired image using the Pen tool and paste it into position, being careful to create smooth edges. If needed, add a new layer and use the Brush tool to smooth out some of the tones.
 

15 The final touch is to add a slightly textured background. I created mine by photocopying a printed gradient several times so that it degraded. I then pasted this in place and used the Multiply tool to add a layer of colour.
