Step 8 I used the Airbrush again here – at a Master Diameter of 100 pixels – to apply a gradient to the coloured strokes to give them more tone and volume. Colour adjustments were easy to achieve using image adjustments such as Color Balance or Hue and Saturation. 

Step 9 After I finished creating the line art elements, I began painting a base layer of each of the painted elements. I separated each object layer-by-layer to make painting them easier. Again I used the Airbrush to create tonal gradients.

Step 10 To create additional elements such as the musical notes, I drew and airbrushed these in a separate document – before copying and pasting them into the main composition.
