Step 2 – Yellow and grey body bits
 

• Reserving some white paper centrally (for highlights), wet the first yellow section lightly with clean water

• Drop in warm yellows and allow them to spread naturally

• Add burnt sienna at the top and bottom edges

• Use a cocktail stick to lightly flick out some fine hairs all around the yellow section

• Repeat for the remaining yellow section and the grey part at the bottom

• Let this area dry before tackling the dark segments with the same method.  Remember to leave a little white gap (1mm) between yellow and black for now.  
   

Step 3 – Wings

​

• Keep the wings light and transparent

• ​Add a little creamy burnt sienna where the wings join the body.  Use a clean brush  to lay down water ahead of this paint.  Push the water back into the burnt sienna to encourage it to gently bleed outward

• Use a very diluted warm grey or yellow wash to fill in the top wings - leave some clear areas as wings are translucent

• Add a few delicate vein lines using the cocktail stick or any handy pointy thing
  
  DRY

• Repeat for the bottom wings but alter the colour slightly so it leans in a purple direction
  
  DRY

• Once bottom wings are dry, add a cast shadow beneath the top wing, if needed
   

Step 4 – Legs & Antennae​
 

• Use quick, confident, thin to thick brush marks for the leg segments

• I like to pick up a light grey on my brush then dip the end in raw sienna.  This give me some interesting colour mixes on the legs

• Keep legs slightly broken and expressive rather than heavily detailed.  I find the hairy ones a bit scary ha ha - but if you want to keep it authentic, flick out some hairs with the cocktail stick

• Drop some additional colour in here and there if you need, but remember to keep some light areas too

• Add the antennae with the tip of a fine brush
