When you browse through [url removed, login to view] you will see that although many of the icons are flat, they use lots of detail to give the effect of depth and contrast. For the icon, I would like for you to play around with the colors being used in the app. You can make a fill behind the eyes, or change the blue, or even play with the shapes or come up with something slightly different.
The logo and the icon should be complimentary but you don't have to show the entire logo in the icon. For example, the Duolingo icon [url removed, login to view] is only part of the logo.
The budget for this is $80, which includes at least 3 design directions for both the icon and logo. We will then select one direction and make any final adjustments based on feedback. Let me know if you'd like to proceed.
