Heatwave iOS icon @2x

I've not designed an icon in a while and had some time on my hands today, so I came up with this concept for a weather app icon, called "Heatwave'. I wanted to major on the sun/heat aspect to weather, and so used a colour palette that fit with the idea.

As always, open to feedback and changes...this one was just for fun, but the @2x will give you a better sense of the icon, especially the background which took me AGES to get right.

Thanks guys
