This is my first attempt at blockshading, so it's not very good. To make it more interesting, and because I wanted to have some script involved, press space to change the colours.
I learned how from "How to blockshade" by @Glitter15. Unfortunately she must have unshared it because I can no longer view it. In the studio "Blockshade Art!" I saw a project by @IamLakshmeesh called "Apple block shade" and that inspired me to do an easy fruit.
