DailyUI Day 5 - Design an App Icon

This is the app icon for the app I am working on in my Google UX Design course. I am challenging myself to work quickly in the 100 Days of Design challenge -- partly because I just don't have that much free time and partly because I want to push myself to design more quickly. Often the difference between pro and amateur is not the quality of the work but the speed at which high quality work can be produced. So I'm shooting for 15 minutes per design during the 100 Days of Design challenge from DailyUI.
