Step 5 Create a new layer called ‘Spheres 4’ in the Colour Spheres group. Using the Ellipse tool (U), make a circle around part of the model’s head in this layer. Hit the ‘Lock transparent pixels’ button on the Layers panel. Select the Gradient tool, set it to a radial gradient of black-to-white, and apply it to the circle. It should now look like a sphere.

Set the layer’s blending mode to Overlay, with an opacity of 85%.

Step 6 Duplicate ‘Spheres 4’ three times so you have layers beneath named, from bottom to top, ‘Sphere 1’, ‘Sphere 2’ and ‘Sphere 3’. Make the spheres in these layers solid green, solid brown and a gradient of varying blues, respectively.

To add a bit more colour and interest to the head area, set the opacity of the new layers to 45% while leaving the blending modes set to Overlay. Offset the green and brown circles slightly.

Step 7 In Illustrator, select the Ellipse tool and draw a simple oval, with no fill colour. Use a 3pt dotted black stroke with a 2pt dash and a 5pt gap for this. Copy the oval and paste it into the Orbs group in Photoshop, calling this layer ‘Track 1’.
