Looking at just the wing, I would do the yellow first, just 1/4" past where the blue starts. Then the blue (black?) to 1/4" past the red. Then the red. Then I would lay yellow squares on top of the red at the tips.

The squares is the only area you would have to worry about seams lifting, because by working from back to front, the air would not be able to lift the seams. As for the squares, some clear Lustercoat would help hold them down, But I would probably just leave them alone and hit them with a hot iron whenever needed.
