I really enjoyed these projects. The luna moth took me a while, but I enjoyed every minute of it. It was the last of the series I did and I felt more confident with it than the others. Watercolor seems perfect for these butterflies because of those nice edges and overlaps!
(on this one I tried the blurry blend black edges - it's so fun to do! But I wasn't thrilled with it. And, really, in hindsight it didn't match the actual butterfly. I painted over the edges with crisp black to practice and it looks better. Live and learn.
