Step 6 I wasn’t happy with the color scheme at this point, so I added add a red-green Gradient Map adjustment layer. If you do this, use a Lighten blending mode at 100% opacity.


Step 7 The artwork is still a little plain. To give it more depth, create a new layer and set its blending mode to Screen. Use a large round soft brush in a light blue colour and paint on the areas you’d like to brighten.

Create another layer and set its blending mode to Soft Light at 58% opacity. With your brush’s colour set to black, paint on the areas where you want to darken the shadows.
