I have an app called "primal days" that lets those following the paleo or primal lifestyle track their daily habits such as eating well, getting sunlight, moving, lifting, playing, etc.
The app uses petroglyph style art (which won't be changing) that is hand-drawn. But the sun icon that is used now doesn't work well for the app icon.
I'd like to continue to use the idea of a sun and a petroglyph style to emphasize the daily habit style of the app.
Needs to be 1024x1024, but also look good down to 57x57 pixels.
The attached file shows the current icon above (on a blue-gray background from the iPad, ignore that), and the current (not changing) app screen/colors/graphics below.
