08. Time to add some contrast: add two adjustment layers to tweak the colours. The first affects hue and saturation: go Select > Layer > New Adjustment Layer > Hue/Saturation, and set the hue to +71, the saturation to –83, and the lightness to –19. For the second adjustment level, go Select > Layer > New Adjustment Layer > Levels, and set the input levels to 34 for dark areas, 1.00 for midtones, and 233 for light tones. Set the output levels to 0 and 255 respectively.

09. Double-click on the foreground colour (at the bottom of the Tools palette) and enter the value #f5f74c in the colour picker. Using the Pen tool create a yellow swirl, then right-click (Ctrl + click) on the layer and choose Rasterize Layer from the dropdown menu. Now go Select Layer > Layer Style > Drop Shadow and enter the following settings: blending mode – Multiply; drop shadow – 45%; angle – 30º; distance – 14 pixels; spread – 7 pixels; size – 21 pixels; global light – ticked. In the Bevel and Emboss menu of the Layer Style palette enter the following values: style – Emboss; technique – Smooth; depth – 429%; direction – Up; size – 73 pixels; soften – 0%. In the Shading section of the same menu, set the angle to 30º, the altitude to 30%, the highlight mode to Screen at 0%, and the shadow mode to Darken at 32%. Experiment with the values to get an effect you like.

10. Open the eye image and drag and drop it into the canvas. Add a layer mask and remove the unwanted areas around the eye, then rotate it slightly as shown here. If you want you can make a selection around the green area of the pupil and adjust the image levels slightly to brighten it (Select Image > Adjustments > Levels).
