Zephyrus's Embrace Picture

I had to draw "wind," so I had to come up with a way to illustrate something that's invisible. I ended up turning to Greek mythology. Zephyrus is the western wind. His wife is Iris, the goddess of rainbows. So I drew Iris embracing her husband.

I haven't worked with colored pencils in a long time. I've seen people do amazing things with them, but they just don't do anything for me. Still, it was fun. Any advice is welcome.
