The primary use of the design would be for a iTunes logo, and so the art  "must be in the JPEG or PNG file formats and in the RGB color space with a minimum size of 1400 x 1400 pixels and a maximum size of 3000 x 3000 pixels."  Beyond that, we're looking for something that is easy to read at a small scale, as most people would be viewing it as a small icon on a phone. 
We don't have a color scheme preference, and are open to anything you think would be a great logo!

Arturo was great to work with! very responsive and able to meet all our requests. We are very happy with our design.
