Before and after shots, rather, beginning and close to end-
painted in GIMP, using paths to make the streaks or bands. Really like the way it came out, the image on the right is for comparison.
I then layered blue underneath for the contrasting stripes.
the next challenge is to get the stippling right; the subtle degradation of yellow into blue/green.
You can see the green wash in the above image that is the start of that coloration but I'm not sure how to achieve the look on the grasshopper.
