I love music, and I love bright colours plus it's summer so I thought I'd make something which to me represents the feeling I get when I listen to music: passion, energy, love, life and melancholy.
To me orange means energy and freshness, red is passion, blue is life (water, sky) and also represents 'the blues' -- sad and melancholic music, which I also love.
It took me quite a while to make the swirls, anker point by anker point, making sure they were slightly overlapping at the edges. My original idea was to make the swirls with ornate music note patterns, but it proved too time consuming.
Anyway, I wanted to keep it simple and think it works -- for me anyway.
