I have a personal rule: "everything that can be customized, will be". As I spent way more time than I should making these for my iPad, I thought it'd be a good idea to share them so other people can use them as well. The .ZIP file you can download here contains 14 unique icos and their respective original illustrations in .PNG in case you want to edit them. It also includes the background image seen in the screenshot, the illustrations I used on the widgets and an extra background image. If you use them, feel free to share a screenshot with me!
The screenshot was taken from an iPad 9, in case you don't know how I customized the icons on iOS: I used the app 'shortcuts' to create a shortcut for each app. You can find tutorials on how to do this on YouTube.
