It's not my first time seeing this but the use of 'illustration' in product design is very important nowadays. Most of us designers are eager to craft the simplest and most intuitive user experience.
Chris Reath shared some incredible illustration work on his Dribbble profile most of them featuring strong contrast with some vibrant accent colors. In addition to that he beautifully worked with isometric perspectives. The result is some stunning compositions like the "paint the black hole blacker" and "An Ode to Radio Raheem". The latter was a homage to Bill Nunn.
