I love how the lower wing looks, the shading is much nicer than the upper wings. I refuse to start over so I might just touch up the shading on the upper wings.

For the upper wing, I had 3 distinct sections, one for each color, and filled all with a 4-strand long&short. For the lower wing, I did distinct sections for only the light and dark color (4-strand long&short) and sparingly added the in-between color afterwards (2-strand long&short). I feel like this method looks way more organic than the first attempt, and still allows me to use 4 strands to cover the bulk of the area.
